When reading the release notes for PVM 3.3.0, I was excited to hear
about the pvm_catchout() command, as it sounded like exactly what I've
been faking using various methods that haven't been completely
satisfying.

However, upon getting the new user's guide, and giving is a whirl, I
was dissapointed to find that lots of glarp was tacked on to what I
was trying to print (namely all the [txxxxx] notations and the BEGIN
and EOF markers).

I realize that these can be helpful at times, but they can also make
output completely unreadable.  Most of the real parallel machines that
I've worked on have supported printing by all children to a single
console, without any indication of who is printing, allowing me to
have several processors working together produce one coherent stream
of output.  Shouldn't there be an easy way to do this on a virtual
parallel machine?  (Or is there?  Am I missing something?)

Is there an easy way (short of src modification) to turn off this
	feature of annotated output?

Are other users annoyed by this, or is output not so important to most?

Has anyone developed an elegant method for child processes to print to
	a single console that they'd be willing to share?

Thanks!
-Brad
