[PD] [comport] crashes on Windows

[Hans-Christoph Steiner]

I have incorporated the "OVERLAPPED" asynchronous mode code for  
Windows from Piotr Majdak in the [comport], and now it crashes pretty  
regularly.  I just committed the comport-stress-test.pd, which makes  
Pd crash within a couple minutes.  It seems to be caused by  
transferring a lot of data from Pd to the serial port.  FYI: I am  
using an Arduino to test.

I did a little test to see whether its the new code, or whether there  
were crashes before.  So I compiled revision 1.10, which uses the  
standard synchronous mode for data transfer.  This version seems to  
last a bit longer, but it crashes in a much uglier way: it zombies Pd  
and doesn't let go of the serial port.  So its an improvement, but  
still, it crashes a lot.

Any of you Windows hackers want to take a stab?  I am going to test  
things on Mac OS X now.
