When I run Chimera on OS X 10.5 "Leopard", I get a ton of the following errors in /var/log/system.log: The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec(). Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__ () to debug. I first reported on this on November 2, 2007, but with the latest daily build this still happens. I removed all extensions, but that doesn't seem to make a difference. My own extension becomes painfully slow, because Chimera is constantly writing the above error message. I never get the error above with the version of python that comes with Leopard or with the version of python2.5 in MacPorts. Would it be possible to build Chimera's version of Python similar to these other versions of Python? Or does the problem lie elsewhere? -- Mark
