Section 18.9 of the FAQ says:

"You might consider disabling virtual memory to make sure your program
doesn't page.  To accomplish this, either set the `_CRT0_FLAG_LOCK_MEMORY'
bit in the `_crt0_startup_flags' variable, or use `CWSDPR0' or `PMODE/DJ'
as your DPMI host."

I hope this solves the problem.
