cpuhotplug_07 produces too many results

[Milosz Wasilewski]

In some cases cpuhotplug_07 produces as many as ~100k results. This is most likely due to problems with udevadm. Sample output below:

cpuhotplug_07.30/cpu1: warning: udev monitor not running... skip

waitfor_udevadm() is running a while (1) loop waiting for udevadm data to be available.

 52 # damn ! udevadm is buffering the output, we have to use a temp file¬
 53 # to retrieve the output¬
 54 rm -f $TMPFILE¬
 55 udevadm monitor --kernel --subsystem-match=cpu > $TMPFILE &¬
 56 pid=$!¬
 57 waitfor_udevadm¬
