okay, now I see that this lacks a lot of "presentation".

This is a patch to fix a problem on signal masks, and solves a certain
problem when the client is "playing the game" of sigsegv mask/unmask.
I will explain it a little more on a better patch. This should have
been explained on the 00/00 cover. And, moreover, this is kinda the v2
of a single-mail patch.

Before sending a v2, is there something more that I should correct?
And one netiquete question, test-breaking code should be in the
description (cover, 00/00)? On a next post in the same thread? Another
thread?
