I need some advice on Bug #153070

Bug #153070 [0] was reported a few years ago.  I am now the maintainer
of toshutils and am trying to resolve this bug.   I can reproduce it
very easily.  Thing is I am not sure if this is really a bug or if it is
the correct behavior.  Essentially, if the pid file already exists in
/var/tmp and the program is not already running, and you run hotkey, it
emits a warning, removes the pid file and runs.  On the other hand, if
the pid file exists and the program is already running, it sends a
SIGUSR1 and exits with status 1.  Here is the relevant code from main():

  if (!access(PID_FILE, R_OK)) {
    if ((str = fopen(PID_FILE, "r" ))) {
      fscanf(str, "%d", &pid);

      /* test to see if the other hotkey is still running */

      if (kill(pid, SIGUSR1)==0) {
        fprintf(stderr, "hotkey: Already running as "
                "process %d.\n", pid);
        return 1;

      fprintf(stderr, "hotkey: process %d appears to have "
        "died, continuing\n", pid);

It is obvious that the way the program is behaving the bug report is
they it is programmed to behave.  I would like to know if there is a
better way to handle this.
