.SH BUGS
In kernels before 2.6.37, a
.I timeout
value larger than approximately
.I LONG_MAX / HZ
milliseconds is treated as \-1 (i.e., infinity).
Thus, for example, on a system where
.I sizeof(long)
is 4 and the kernel
.I HZ
value is 1000,
this means that timeouts greater than 35.79 minutes are treated as infinity.
