I'm running a code under PVM 3.3.3 which uses dynamic process groups.
The first time I run it after starting the PVM daemon, it hangs with
the message

     libpvm [t40007]: pvm_exit() child task(s).  waiting...

If I interrupt and rerun, it works all subsequent times, so long as
I keep the daemon running.  It appears as if it needs to have pvmsg
already running.  This is true whether I run it on RS/6000's, or
SP1's.

Another, simpler code that uses dynamic process groups runs fine
every time, even the first.

Any idea what the problem is?
