ualarm() and ptys.

[Kevin Lincoln Flynn]

ARRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!

<sigh>

We're running about a dozen 3B2's here.  There's a program I'm working on that
I want/need to port to some of our 3B2s -- among other things, it is a light-
weight thread scheduler.  I need the equivalent of ualarm() for it -- ie an
alarm() call that can send me a SIGALRM every 1/10th of a second or so.  Now,
the man page for clock or something tells me that the 3B line has a clock res-
olution of 1/100th of a second....  so WHERE THE !@#!@&* is a call or function
or kludge or _SOMETHING!!!!_ that can get at it?!  Using alarm() and just
making do with nonpreemptive scheduling is not acceptable.

On another note, does anyone have a pty driver and Unix-domain sockets that
will run WITHOUT Wollongong TCP/IP?  We're looking at perhaps MAYBE using
3BNET for RFS but need ptys to be able to do real interactive logins.

Thanks in advance (sigh),
