RE: problem with parallel builds on AIX

There is only one issue I know of with the implementation of the
jobserver in 3.79.1: it allows signals to interrupt system calls
throughout the program.  This can impact things like readdir(), etc.

But, while this does cause some problems sometimes I've never known it
to cause a jobserver hang.

I added a solution for this into the CVS tree (actually I proposed the
solution for discussion on the make dev list and before I could write it
myself Paul Eggert sent me a patch that implemented most of it--I only
had to tweak it a bit :)), so GNU make in CVS no longer has this issue.
I suppose it wouldn't hurt to try it and see if it solves your problem.
