It's a fairly simple matter to drop in a version of malloc which is truly multi-threaded, removing the locks in the malloc wrapper. Figuring out which malloc is the best and insuring that we haven't broken anything which relies on the subtle behavior of dlmalloc isn't. Maybe that's what you're saying. One gotcha is that some multi-threaded mallocs use memory profligately. So, that's something that we have to be aware of when we change mallocs. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
