- #1 doing some "complex" long unit test, and, unfortunately, it does not correctly clean its temp stuff after completion (too bad, but I cannot affect this behavior).
- #2 checks for free space on the drive, and, if below some threshold, its event handler cleans all the temp dirs, removing also all the garbage produced by #1.
What I want is to make sure these two checks never run at the same moment. I cannot tell whether #1 is running when #2 is attempting a cleanup, so #2 can easily blow up an active run of #1 (and #1 is of more value to us).
Do I have any options here?
Important notes:
1. setting non-overlapping time-periods for both checks proved to be unreliable - time periods only limit the start times, there's no knowledge whether the affected check (#1) is still running or has completed. Moreover, we'd like to keep the more-or-less random check start times.
2. I know that I can set a similar event handler in #1 making the cleanup immediately after the check itself completes. However, I cannot disable #2 at all , and there's still a risk that it will crash a running #1 by erasing its scrap data.
Any ideas are welcome.
