signalfd.2: Note about interactions with epoll & fork
...
Using signalfd(2) with epoll(7) and fork(2) can lead to some head
scratching.
It seems that when a signalfd file descriptor is added to epoll
you will only get notifications for signals sent to the process
that added the file descriptor to epoll.
So if you have a signalfd fd registered with epoll and then call
fork(2), perhaps by way of daemon(3) for example. Then you will
find that you no longer get notifications for signals sent to the
newly forked process.
User kentonv on ycombinator[0] explained it thus
"One place where the inconsistency gets weird is when you
use signalfd with epoll. The epoll will flag events on the
signalfd based on the process where the signalfd was
registered with epoll, not the process where the epoll is
being used. One case where this can be surprising is if you
set up a signalfd and an epoll and then fork() for the
purpose of daemonizing -- now you will find that your epoll
mysteriously doesn't deliver any events for the signalfd
despite the signalfd otherwise appearing to function as
expected."
And another post from the same person[1].
And then there is this snippet from this kernel commit message[2]
"If you share epoll fd which contains our sigfd with another
process you should blame yourself. signalfd is "really
special"."
So add a note to the man page that points this out where people
will hopefully find it sooner rather than later!

...
Quoting Branden:
*roff escape sequences may sometimes look like C escapes, but that
is misleading. *roff is in part a macro language and that means
recursive expansion to arbitrary depths.
You can get away with "\\" in a context where no macro expansion
is taking place, but try to spell a literal backslash this way in
the argument to a macro and you will likely be unhappy with
results.
Try viewing the attached file with "man -l".
"\e" is the preferred and portable way to get a portable "escape
literal" going back to CSTR #54 , the original Bell Labs troff
paper.
groff(7) discusses the issue:
\\ reduces to a single backslash; useful to delay its
interpretation as escape character in copy mode. For a
printable backslash, use \e, or even better \[rs], to be
independent from the current escape character.
As of groff 1.22.4, groff_man(7) does as well:
\e Widely used in man pages to represent a backslash output
glyph. It works reliably as long as the .ec request is
not used, which should never happen in man pages, and it
is slightly more portable than the more exact ‘\(rs’
(“reverse solidus”) escape sequence.
People not concerned with portability to extremely old troffs should
probably just use \(rs (or \[rs]), as it means "the backslash
glyph", not "the glyph corresponding to whatever the current escape
character is".
