long (25 seconds) pause when starting hal-device-manager

So it seems my patch did not fix the issue.  It is really weird due to
the fact we get stuck in poll once consistently and then all subsequent
calls just go happily on their way after the poll times out.  It really
has been a pita to debug.  I know what causes it.  We fire off an
introspect under the hood and then block for it to return if a blocking
call is made.  This works fine for three of the calls which introspect
the bus but we block on the first introspect to HAL.  Funny thing is if
we don't connect to the signals (the cause of the first three
introspects) everything works fine.  Also if we block for introspect
immediately, instead of waiting for a blocking call nothing bad happens.
Workaround is to add result[1].block() to the end of the _Introspect
method in proxies.py.
