Subject: procd: Switch to nanosleep
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=8e9fb51fa66e614620a97d371176610e7e1d0010;p=oweals%2Fprocd.git

procd: Switch to nanosleep

usleep has been deprecated by POSIX.1-2001 and removed in POSIX.1-2008.
Fixes compilation when libc does not include usleep (optional with
uClibc-ng).

nanosleep also has the advantage of being more accurate.
