Speaking of which, it would be nice if rpy was shipped with a vanilla locking mechanism.
R remaining probably thread-unsafe for the foreseeable future, I was thinking of having something like a two-locks mechanism that would lock R and release Python's GIL whenever an access to R is made. The expected benefits are: - explicit error message when someone tries a multithreaded approach (currently, I suspect that what is happening in such a case is unpredictable) - ability to have some level of parallelization where python-ish things can still be done while R is busy (useful for GUIs, or for cases where preparing a next batch of data can be done by python while R is still computing on the current batch) The downside I am seeing is it will make the handling of Python callbacks (python functions passed to R functions as arguments) complicated (if possible). Ideas, or help, on the matter are welcome. L. 2008/6/26 Gregory Warnes <[EMAIL PROTECTED]>: > > Hello Laurent, > > The R system itself is not thread safe, and has quite a bit of persistent > state.
