Has anyone out there used function 67H (Set Handle Count) of DOS interrupt 21
to increase the number of files a process can have open at one time?

This interrupt was added in DOS 3.3, and I know I have to enlarge the PSP (with
function 4AH(Set Memory Block Size)), but I'm not sure what size I should be
enlarging it *to*.

I'd like to be able to do this as part of C-program, using the C-function
intdos() to invoke the appropriate DOS interrupt.
