Hi Dave,

I'm sorry to say this, but I think you're on the wrong track.  Instead
of replicating bits from the obsolete inftarg.c, this should really be
implemented as a threads stratum, much in the same way as
bsd-uthread.c.

I'll see if I can hack something up for you along those lines.
Unfortunately the HP-UX 10.20 system that I have access to, doesn't
have the threads stuff installed, so I can't test things.
