[Numpy-discussion] [Patch] Fix memmap pickling

[Gael Varoquaux]

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
