Signal handling appears to be broken. Here's a simple testcase. Run the pro=
gram
and hit control-c. It'll print "got Alarm clock", then stop accepting any
signals at all, even SIGSTOP. The same program works fine on my Debian stab=
le box.

#define _GNU_SOURCE 1
#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <pthread.h>

int
main()
{
    sigset_t waitmask;
    int sig;

    sigemptyset (&waitmask);
    sigaddset (&waitmask, SIGINT);
    sigprocmask (SIG_BLOCK, &waitmask, NULL);

    for (;;) {
        sig =3D sigwaitinfo (&waitmask, NULL);
        fprintf (stderr, "got %s\n", sys_siglist[sig]);
        if (sig =3D=3D SIGINT) {
            break;
        }
    }

    return 0;
}
