There are two reasons why this shouldn't happen:
1) our PostMessage() just uses SendMessage()
2) our SendMessage() just moves the message into the internal looper
queue regardless of the port queue
So if your app was locked in PostMessage(), it should have been another
reason - but it would still be nice to know which one that was :-)
