Log Message:
There is no need to resize the pollfd array, it can only ever have 2+maxJobs
entries, so allocate at startup.
Use an 'int jobPipe[2]' within the job structure, and create pipes directly
into it.  Common up the code that creates all the pipes - making them all
non-block on the read side in the process.
Call Job_CatchChildren() directly from Job_CatchOutput() so that it only
gets called when a child actually exits.
NB: Something causes a 'pregnant pause' if (for example) you call 'nbmake obj'
in src/tools.  Introduced between netbsd 3 and 4.
