Changeset 3107 for trunk/packages/vizservers/vtkvis

Message:

Don't print error when sem_wait is interrupted, instead loop on sem_wait while
errno == EINTR. This doesn't change the previous behavior of the writer thread,
but it suppresses a syslog error in the case of the sem_wait being interrupted
by a signal.
