Cycle 1.7.6, day #4 of week #7

Was sick most of the afternoon, so not much done, except for:

• found many misuse of zlib API in our code that assumed we can feed more than 4GB at once to inflate/deflate, which was not a case;
• fixed a few instances and sent patches to the mailing list;
• commenting on a few topics on the list.

Queued 4 patches from 2 people.
