Alas I don't know a mechanism to deliver an interrupt.  If there's a mechanism I can implement the stack trace.  Anyone have any suggestions?

Does the cygwin `kill` command work with USR1 when run from a cmd.exe prompt? 
Could that executable just be included with distributions in the same folder as the VM?

Just for reference, Apache simulates USR1 with its own program ([1] search for 'equivalent')

I'm not very familiar with this area, but I poked around for interest and summarize a few findings. Sorry I'm not set up to experiment with them myself.

The UNIX Application Migration Guide [2] provides some alternatives (click 'Signals and Signal Handling')
Someone provides an alternative at [3] - but I don't follow it.
There is some discussion at [4], which references [5] as a possible option.
Another alternative a [6].

Hi Eliot,

On Mac and Linux one can get a stack trace from a busy VM with the USR1 signal. Is there an analog on Windows?
