Description:
------------
Some tests may fail due to process timeout in docker (debian:buster) on windows host via WSL2 (ubuntu) when executed on bind mount from host:
=====================================================================
FAILED TEST SUMMARY
---------------------------------------------------------------------
Bug #79514 (Memory leaks while including unexistent file) [Zend/tests/bug79514.phpt]
Bug #36365 (scandir duplicates file name at every 65535th file) [ext/standard/tests/file/bug36365.phpt]
=====================================================================

Problem seems to be that the 9p (plan 9 / network) filesystem is very slow under pressure and both tests are either creating or looking up thousands of files, which makes those tests fail with a process timeout rather than an actual error or lockup. When executed individually they do succeed (on my pc):


$ time /workspace/php-src/Zend/tests/bug79514.sh 
bool(true)

real    0m42,861s
user    0m2,512s
sys     0m7,781s

$ time /workspace/php-src/ext/standard/tests/file/bug36365.sh 

Warning: mkdir(): File exists in /workspace/php-src/ext/standard/tests/file/bug36365.php on line 4
int(70002)

real    2m7,388s

Actual result:
--------------
