The plugin hangs with patch 1532 because genmon_Spawn() is waiting for I/O when
there will be none.

With the patch, strace shows that genmon calls waitpid() and then hangs at
poll(). Here's how to confirm.

Configure a genmon command script to call /bin/true on click and set the period
to one second. (Attachment follows.)

$ ps -e | fgrep genmon
26211 ?        00:00:00 xfce4-genmon-pl
$ strace -p 26211 -f 2>x.log

x.log has these lines:
...
[pid 26360] execve("/bin/true", ["/bin/true"], [/* 40 vars */]) = 0
...
[pid 26360] exit_group(0)               = ?
Process 26360 detached
--- SIGCHLD (Child exited) @ 0 (0) ---
waitpid(26360, NULL, 0)                 = 26360
poll( <unfinished ...>
Process 26211 detached
