: o Remove them and add a commet that documents their previous existance.
: o Rename them to freebsd3_sigaction() and freebsd3_sigprocmask() and
: reimplement using split syscalls.
: o Move them to the 43bsd compat tree and reimplement using split

:question becomes whether we should keep FreeBSD 3.x compat bits in the

I *think* we can simply scrap them. The only compatibility we really
