I think your problem is perl's safe signal handling introduced in 5.8.0 or so.
I have tried
<PERL>
$SIG{USR2}=sub {
warn "USR2: @_: $$";
};
</PERL>
in my httpd.conf with 5.8.0 and 5.005_3 on linux. With 5.8.0 I get the message
from the signal handler only at server shutdown. With 5.005_3 it appears
immediately.
With 5.8.0 signals are delivered only between opcodes. Since apache's main
loop looks to perl like a very long running opcode the signal is delivered
only at shutdown.
Maybe you can achieve your goal using POSIX::sigaction. I haven't tried it.
