  Without testing it you have no way of knowing whether that is important or
not.  It could be that there's an interaction in cygwin when separate
processes both try and take mutexes at the same time for example, perhaps they
both need to access some locked structure in the shared memory and one of them
is forgetting to unlock it for instance?

  Making assumptions is not the scientific approach, doing experiments is.

  Yes, absolutely so.

  Also correct.

  Utterly comprehensively wrong.  Sorry.

  The only thing that "does not constitute distribution" is giving it to other
individuals within your organisation; if I worked for the same firm as you,
you could give me a binary without that conferring gpl rights on me, because
basically it counts as keeping it private.

  I fully understand; your hands are tied.

    cheers,
