[gobolinux-users] Prevent a process from paging out

[Carlo Calica]

man 2 mlock

It'll require patching the source.  A quick ugly hack would be:

add "#include <sys/mman.h>" with other headers
add "mlockall(MCL_FUTURE)" towards the beginning of main()

Good luck.  If you have problems check the return code, also see the
section on Limits and permissions in the manpage.
