Core dumps if pvm is not running (so does a C program).  It would be
cool if I could check if pvm is running upon initializing the module or
provided a check_up function.

Core dumps when runnung master_test.py because exit core dumps!
Exiting the pvm client also core dumps.  So do C programs.  This has
the side affect causing the slave to dump core and catchout not to work.
Seems to be a problem with PVM, I have tried several RPMs, build PVM my
self and it always behaves the same.  Perhaps caused by using glibc 2.1?

Add rest of PVM functions.
Add new 3.4 stuff (see pvm web page).

Finish converting to gnu build system (wait for Python support).
python1.5 is hard coded into spec.in file.  Building dynamic python
object is hard coded in Makefile.am.  Add INSTALL file.
