I've installed a current built last night and job control no longer
works in /bin/sh or /usr/local/bin/zsh, but it does with csh. ctr-c and
ctrl-z are just ignored with both the sh style shells.
[Same experience here, with a guess at what is causing this. My system is
an IBM ThinkPad X20. Note I am not really a kernel hacker, and the move in
CURRENT to threads has really dated my knowledge.]

Moving from FreeBSD 5.1beta2 to a slightly post-release CURRENT signals
have stopped working under bash and sh for ordinary users (but not for
root). Creating a user from scratch verified that the problem did not stem
from initialization process problems.
The following patch to trap.c might have a failure in the logic by
replacing the call via PCPU_GET(spinlocks) by the direct reference to the
thread-critnest, but this is just a guess.

A screaming comes across the sky. It has happened before, but there is
nothing to compare to it now.
