Re: [openMosix-general] openmosix-2.6

Evan,
  This won't affect the interface the omtools use.  This 'merely'
removes the node communications from the processes themselves and
centralizes it.

working on it and the foundation is mostly there.

I need help looking for bugs and bad design decisions on my part.   I'll
start modifying the rest of the code to use it after that.
