Would there be much downside letting users do the equivalent of

  signal(SIGQUIT, SIG_IGN);

? And likewise for SIGHUP, SIGUSR1, SIGUSR2.

And while I'm asking, how about letting users do

  signal(SIGINT, SIG_DFL);

for cases where you don't want SBCL's SIGINT handler?

Note that I'm only thinking about the two handlers defined in the C
standard, not arbitrary user-defined ones.

Thanks,
Richard
