This informative assertion failure means the jthread system
This is presumably so because jthreadedFileDescriptor failed.
This could be the case because the FIOSSAIOSTAT ioctl failed.
I don't really know what that does, and it's hpux only, it's only
in there because I saw it in some other package that uses async IO
under HPUX. Could be that it fails for tty fds, and is only needed
for sockets or files or something. I don't know. If you find out,
send mail. The possible fix would be to not check the return code
of this particular ioctl. (Also, you might want to add a "perror"
to see what's going on; this needs to be done anyway.)
Btw, if you compile with "make EXTRA_CFLAGS=-DDEBUG", jthread.c will
keep the stdio fds synchronous, meaning that jthreadedFileDescriptor
is not called on them. You should try that. If you're debugging, but
need the fds to be asynchronous, give it -vmdebug ASYNCSTDIO.
I remember testing jthreads without Kaffe on some 9.x version of
HPUX, but not very thoroughly.
Hope that helps,
