Some of these may be available:

Signal          Comments
SIGWINCH        MUD shouldn't receive a window resize if in background.
SIGINT          You won't be able to CTRL+Z the MUD anymore, use SIGSTOP.
SIGTRAP         GDB will be useless.
SIGPROF         Don't profile (-pg in gcc) your code.
SIGUNUSED       Duh.

Not all may be available and I haven't tested the above.
