I really thought about this over night.
I'm a C programmer and thus:
- Produce no bugs
- If you've produced a bug, fix it at once
- If you've fixed a bug, scream out loud "BUGFIX!" -
or at least incorporate the patch in the very next patch release
But i have no experience with maintaining a scripting language.
My survey of something like this spans about three months now.
And if even such a heavy known bug as #1202 survives at least two
minor releases (2.6 and 2.7) without being fixed, then maybe no
more effort should be put into 2.7 at all.

11277-27.2.diff uses INT_MAX and thus avoids any such pitfall.
Maybe it brings up memory mapping errors somewhere which i surely
would try fix everywhere i can.
