Because it's a non-cygwin child process, cygwin doesn't realise it's started and crashed, it thinks the process creation suffered a temporary failure and has up to 5 retries. > > I was wondering, is this a bug or a feature?

Recompile the dll, with attention to sigproc.cc: int child_info::retry_count = 10; and the way that child_info::proc_retry decrements the 'retry' counter which is initialised to that value.
