I gave the snapshot some testing today.

The good news is that the named FIFO branch of our code works correctly
again and is faster than going through pseudo-file STDIO pipes.

The bad news is that there is still some problem that seems to hit while
forking.  I've got an empty stackdump file from sh (which gets used when
exec'ing due to the way perl implements that) a few times and also one
error message about a terminated thread due to "Windows WFSO error 6"
(hilariously the output file was produced correctly in that case).  But
most of the time the processes in my data pipeline would all have execed
correctly, but then none of them ever gets runnable again.  So this
seems to be something of a race around the exec.  If I kill the stalled
processes and start the same commands again, then everything works as it
should most of the time.


Regards,
Achim.
