If you have a Sun, and are using SunOS 4.1, you could add a function
call to plock(), which, according to the man page:

DESCRIPTION
     plock() allows the calling process to lock its text  segment
     (text  lock), its data segment (data lock), or both its text
     and data segments (process lock) into memory.   Locked  seg-
     ments  are  immune  to  all  routine swapping.

The only drawback is that the process must have an effective user ID
of super-user to make this call.
