My multithreaded Guile is getting cooler by the day. The garbage collector
is bahaving properly, but I still have some signal handling troubles
to work out.

Here's a little C program that doesn't behave properly when I build
and link against 1.60 beta 4.1. It hangs under Linux 1.2.13.
Any ideas? 

---- cut here ----------------------------------------------------
#include <stdio.h>
#include <signal.h>
#include <sys/wait.h>

int gotSignal = 0;

sigProc(sig)
     int sig;
{
  gotSignal = 1;
}

main()
{
  int pid, sts;
  (void) signal(SIGCHLD, sigProc);
  pid = vfork();
  if (pid <  0) {
    exit(1);
  } else if (pid == 0) {
    (void) signal(SIGCHLD, SIG_DFL);
    _exit(0);
  } else {
    (void) wait(&sts);
  }
  printf("%d\n", gotSignal);
  exit((gotSignal) ? 0 : 1);
}
