Nope, it's all cygwin through and through.

Thanks, that's what I'm trying right now. Disappointingly it disappears under strace. That might have been down to the strace-is-a-win32-process-launching-a-cygwin-process anomaly, which is why I'm hacking about the dll. Early results suggest that, even though I'm not launching under strace, but instead enabling it (by calling strace.hello() during initial_env() if I detect an environment variable in the win32 environment), the problem still disappears, which makes me suspicious of it still being a race somehow. cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
