Re: [Pytables-users] Questionnaire

[Andrew S. <str...@as...>]

Given that I'm an "interested and intermittent" user, not a "hardcore, 
must have" user, please don't rank my responses as highly as others'.  
Also, I've only answered the questions that I feel even remotely 
qualified or interested to answer.  (You may take my other answers as "0".)

Sounds great
+1

In conjunction with releasing Python GIL on file write operations: +5

This might make me a hardcore user if I convert my primitive home-brew 
"movie" code. But this would require releasing the Python GIL on writing 
the data to HDF5 files.  This would allow a multi-threaded Python 
program to continue working while the (non-Python API using) C code 
completes. Refer to our previous conversation:

My email (at sourceforge time 2004-06-22 00:04) describes the (seemingly 
fairly simple) necessary changes.  (Sorry, if you've done this already 
-- I haven't kept up with the changes in the last few months.)

Sounds good, but not informed enough to judge (+1?)

(Sorry to keep kicking a dead horse.) Keeping the GIL in long file write 
operations where the Python API is not touched and therefore it could be 
released.
