The runloop provides an array size of 128 ... so you will get this 
exception
if you have connections to more than 128 processes.

If you have fewer processes than this, I think we should start looking 
to
see if we have a leak of handles somehow.

If you *do* have this number of processes, a quick hack is to change the
size of the array in NSRunLoop.m ... but perhaps we should actually look
at redesigning the interaction between the run loop and the port a bit.
