This is possibly/hopefully fixed in win32all-139 and ActivePython 210.

If the problem is what I suspect, and have witnessed using xpcom, then 
the interrupt signal is sent at some time other than when Python is 
executing, but Python's signal handler sees it anyway and sets it 
pending.  When Python is next called, this pending exception is then 
thrown and the COM call fails.

So if this is indeed the case, then ignoring it is reasonable as it is 
not Python code that was interrupted!  And if it is not the case, my fix 
in the builds referenced above will not be a fix at all!

Mark.
