As I mentioned in other thread -- it does not look like CPU load but some I/O (interrupt latency) load which is matter.
E.g. running few busy loops with pegs CPU load to max (400%)
does not increase failure rate noticeably. But running "make check" (that keeps cpu load to 50%) does.

Launching a few (say 4) octave sessions and running the following in each one shows some test failures:

The image returned by "getframe" is empty. What is really intriguing is the absence of warning (see bug #53186). I'll try and look into this tonight.
