Subject: problems with current/smp and signals

Hi,
I don't know if I am sending this to the right address, but I am having
problems with signals on FreeBSD-current/SMP:
this program:
main()
{
while(1);
}
can't be interrupted with Ctrl-C (if it does finally stop, it can take
several minutes)
whereas this program
#include <stdio.h>
int
main()
{
int i=0;
while (1) {
while(i++<100000);
fputs("x",stdout);
}
}
interrupts just fine. Also, and I think related to this, if I have a CPU-
intensive process running on the system (even on one cpu) interactive
response goes down the drain.
Mika
