EINTR happens, if the "read" syscall is interrupted by a signal handler. 
For instance, if a daemon handles SIGUSR to re-read its configuration, and
the user issues SIGUSR in exactly that very moment, the daemon wants to
read from a pipe, the read attempt would fail with EINTR.  Shouldn't happen
that often ...
