.SH BUGS
According to POSIX, the nice value is a per-process setting.
However, under the current Linux/NPTL implementation of POSIX threads,
the nice value is a per-thread attribute:
different threads in the same process can have different nice values.
Portable applications should avoid relying on the Linux behavior,
which may be made standards conformant in the future.
