You do need to be careful with imports and other global side-effects. The last time I did some threaded work in IP, the dictionary structure that contained the imported modules for the engine was not thread-safe. And I don't recall seeing anything committed that would have changed that. If you pre-import the modules prior to forking then it's fine - using a cached module is OK, it's just adding newly loaded modules to the cache that causes trouble. And I'm sure there are other similar situations.
Actual execution of scripts that are side-effect-free is perfectly fine.

Or do i just to impotz and use the thread-module of python. I want to write a script which will read data from a ado.net data-table in memory. it should be able to use all cores available on the host. The only special care you have to take is what you normally would when writing multithreaded code. If you do hit any issues they might be bugs, so please report what you find. - Jeff thanks much and regards bernd -- Mit freundlichen Grüßen Bernd Viehmann Mahrweg 46 41836 Hückelhoven Tel.: 02433 9640 100 Fax: 02433 9640 109 _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org<mailto:Ironpython-users@python.org> https://mail.python.org/mailman/listinfo/ironpython-users _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org<mailto:Ironpython-users@python.org> https://mail.python.org/mailman/listinfo/ironpython-users
