[Scons-users] Random build failure with 'Resource temporarily unavailable' on mac

[Julien Pommier]

It still happens with Python 3.8.3, it seems — I could even reproduce with scons -j1 so it does not seem to be caused by threading issues.

And again… But this strategy does not help with this issue: scons will fail at the same point each time the shell script re-runs it ! However, when I kill the shell script , and launch it again, then scons will most likely succeed. So the issue must depend on some subtle circumstance that I can’t figure
