There is some controversy over whether this is completely reliable, but it seems to work well in my tests, with and without
--max-old-space-size
passed in.I initially tried to just stop adding new programs to the cache at a certain threshold, but somehow memory still shoots up after no more programs are being created at a modest heap usage. So we do this check and purge even if the current
getProgram
call didn’t eat up more memory itself.This fixes the recent openui5 CI OOM.
