testbot flakiness?

[Dan Kegel]

https://testbot.winehq.org/JobDetails.pl?Key=11509 shows failures and
crashes, but the nearly identical
https://testbot.winehq.org/JobDetails.pl?Key=11510 does not.  (The latter one
just adds a call to GetProcessMemoryInfo() in the xyz() logging function.)

And the failure shown by the first patch has a last error
on creating the batch file of 8, ERROR_NOT_ENOUGH_MEMORY, which is suspicious.

Not quite sure what's going on there.
