Cygwin: Speed up dumper 

Stop after we've written the dump in response to the initial breakpoint
EXCEPTION_DEBUG_EVENT we recieve for attaching to the process.

(rather than bogusly sitting there for 20 seconds waiting for more debug
events from a stopped process after we've already written the dump).
