Github workflow failures #144
Description
See https://github.com/python-control/Slycot/actions/runs/522944389
The failure is for Python 3.9, Generic BLAS. The diagnostic is a low-level error that occurs during the python-control tests:
Windows fatal exception: code 0xc0000374
control\tests\xferfcn_test.py .......................................... [ 97%]
Windows fatal exception: code 0xc0000374

Something similar happens in the Python 3.6 Generic BLAS, which is "FAILOK":

Comparing the most recent 3.9 with the same build at https://github.com/bnavigator/Slycot/actions/runs/507101266, there are minor differences (different Github Windows env version, different git version, different build of python 3.9.1, pip 21.0, ruamel_yaml, different version of tzdata, matplotlib, coverage, pytest, urllilb.
The number of tests collected is different, probably due to changes in python-control:

For now I suggest we make Windows Python 3.9 Generic FAILOK too - we're passing Windows Python 3.9 with OpenBLAS and Intel10_64lp.
