I believe there is a system limit of ~64k handles and a per process
limit of ~32k. However, the default per process limit is 20 handles.
This can be increased (but not decreased) with DosSetMaxFH for the life
of the process. All newly created children of the process also inherit
this increased number of file handles.

Additional some C compilers have a limit of 20 fopen's which can only be
increase by recompiling the C runtime initialization code.
