Subject: examples: replace usleep() with nanosleep()

Accessing usleep() requires _BSD_SOURCE feature test macro to be
set. However, _SVID_SOURCE is set as well, what will cause deprecation
warnings when building with glibc >= 2.20. The patch replaced usleep()
with nanosleep() to avoid these problems.
