Yes, I'm painfully aware of that fact and am wondering whether there were a
way to make that work cleanly. I thought about throwing an exception in a
signal handler but doubt that'll work fine and I guess it's going to create
weird side effects. At the moment we use setjmp/longjmp from within signal
handlers to emulate exceptions and it's a considerable performance impact (I
took it out for the UT Linux versions I worked on) whereof the exception
equivalent is virtually free on Windows.

BTW, I get a lot of email sent to me privately and I simply assume it's
meant to be for the list in my replies so add a <private reply> or whatever
somewhere to your replies if you don't want me to reply to your message to
the list :)
