ok thanks.
<evil question>
but wouldn't it be better if the hotplug system did that,
instead of putting the same code into every application?
my app is simply called with the device path to handle,
so I feel like it shouldn't do such retry stuff, but rather
the caller should make sure, that the file given as argument
exists...
so maybe put the sleep/wait functionality into the hotplug
core?
</evil>
