SYNOPSIS
     pbind -b processor_id  pid ...

     pbind -u pid ...

     pbind [ -q ]  [ pid ... ]

DESCRIPTION
      pbind controls and queries bindings of processes to proces-
     sors.  pbind binds all the LWPs (lightweight processes) of a
     process to a processor, or removes or displays the bindings.

This may mean that you need to make sure the lwp libraries are used, ie
lines like 

LD_LIBRARY_PATH='/usr/lib/lwp:/lib:/usr/local/lib:/usr/local/mysql/lib'
export LD_LIBRARY_PATH

Should be included in the 'start' script.

The problem seems to be that the 'start' script starts off zope using an
'exec' command. This replaces the current process (a shell) with the zope
process. Thus adding commands at the end of the script to grab the process
id and 'pbind' it will be pointless as those commands wont get run...

At the moment, I'm 'pbind-ing' manually :(
