Hi Andrew,

Yes, releasing the GIL when writing (or reading) data would be a very nice
addition. I've to look more in depth in that. That would be hopefully
included in version 1.0 of PyTables.

Anyway, if you know how to do add that kind of support, and test it, I'll be
glad to include your code in next version of PyTables.

Thanks for your time,
