[sane-devel] pthread implementation

In sanei/sanei_thread.c there's this little tid-bit of code:
DBG( 2, "pthread_create() created thread %ld\n", (SANE_Pid)thread );
"thread" is of type pthread_t, which is an extremely opaque type. You
won't get a reliable answer by casting it as long and printing it for
debugging purposes. I'd suggest removing or revising this code.
Also, type defining SANE_Pid as type long and setting pthread_t type
variables to this type will result in undefined behaviour.
pthread != pid
pthread_create() != fork()
Looks like all of sanei_thread.c needs work. I'm working on a patch.
