Problems with ForkedProcess::waitForChild()

[Andreas Vox]

Hi!

I wanted to check if the bitmap creation has finished without error
and found out that startScript always returns '1'.

Apparently waitpid() always returns -1 with errno = ECHILD.
Is this a race condition in that the childprocess has finished before
waitpid() is called? If so, the scheduling on MacOSX is peculiar;
it would mean that the whole LaTeX-dvips process outruns the
current LyX thread.

Ideas?
