As you can see from the code, jthreadedFileDescriptor is called for
0, 1, and 2 (the stdio fds) at initialization time, except when debugging
is enabled. This exception is overruled if -vmdebug ASYNCSTDIO is given.
Look at DBGEXPR in debug.h.
After initialization, it will call jthreadedFileDescriptor for every new
fds it creates, independent of whether you compiled with DEBUG or not.
At first glance, your patch looks okay to me. I'll have to look at it
in more detail.

I ran basic tests successfully.

As was pointed out, you have to write it. This is where the crux of
every porting effort lies these days. Writing that will earn you the
title "Official Kaffe HP-UX Porter". Your name and your email address
will appear in common.h for everyone to see. ;-)
Look at i386/common.h, sparc/common.h, m68k/common.h, arm/common.h, and
alpha/common.h for examples.
