lit: revert 134b103fc0 

Revert the 32-process cap on Windows.  When testing with Swift, we found
that there was a time reduction for testing with the higher load.  This
should hopefully not matter much in practice.  In the case that the
original problem with python remains with a high subprocess count, we
can easily revert this change.
