from the man page:
According to the standard specification (e.g., POSIX.1-2001), sync()
schedules the writes, but may return before the actual writ-
ing is done
however the 2.4 kernel will wait until the storage controller has
acknowledged it. It will not wait until the storage hw puts it actually
on permanent media though; that's something that 2.6 does do.
