"On the third try" meaning that you have 2 other subprocesses running,
or did you invoke a process, then terminated it, then invoked another,
etc. 3 times?

Is that for the Emacs process?  If so, I would suspect that GC kicked
in.  You can see if that's so by setting garbage-collection-messages
non-nil.

Did you try increasing the size of the original request in
allocate_heap, and if you did, what was the maximum value that still
gives you a good Emacs session?

Thanks for working on this.
