Limit workers in ProcessPoolExecutor
As a mitigation for #1730, this commit limits the number of workers in
the ProcessPoolExecutor to 1 (default is the number of CPUs). On PyPy,
having a higher number of available workers dramatically increases the
number of concurrent processes, leading to some resource exhaustion
issues.
This does not address the root issue, but should improve the situation
until the root issue is addressed.
