at least not on a POSIX thread.

Why don't you use select and have it suspend the thread until there actually
is some data to read? You can pass a pointer to a struct timeval as a
timeout value. When select returns simply use FD_ISSET to check whether
there really is something to read() (and then do it), otherwise clean up
and exit the thread.
