Not true!  It's possible to exceed the 20 file limit per-process by modifying
the PSP.  It was all described in Dr. Dobbs Journal some time ago.  The PSP
contains a 20-element list of handles, and a pointer to this list.  The
tecnique involves replacing the offset with that of a longer list you have
allocated somewhere, and copying over the handles and filling the unused
list elements.
