Has anyone tried to run "make -j8 ptestlong" on Big Sur? Every time I run
it, doctesting breaks with the following traceback:
Traceback (most recent call last):

OSError: [Errno 24] Too many open files
make: *** [ptestlong] Error 1
Since I was trying to test in parallel I don't know exactly what's going
on, but the last test that was attempted before this error was
sage -t --long --warn-long 53.1 --random-seed=0 src/sage/doctest/test.py
by itself this test seems to pass but causes a lot of random segfaults,
although this is with homebrew's python 3.9.1.
