Last change on this file was 2289, checked in by bird, 20 years ago

o Protect the fork operations by the means of must complete so

signals won't interrupt us till we're finished. This might leave
unkillable processes around if fork goes highwire.

o Better exception logging during fork.
o Use MMX memcpy in fork (if supported).
o The C function libc_Back_processFork() replaces the pure assembly fork().
