[Numpy-discussion] [Patch] Fix memmap pickling

Memmapped arrays don't pickle right. I know that to get them to really pickle and restore identically, we would need some effort. However, in the current status, pickling and restoring a memmapped array leads to tracebacks that seem like they could be avoided. I am attaching a patch with a test that shows the problem, and a fix. Should I create a ticket, or is this light-enough to be applied immediatly? Cheers, Gaël
