-rc6 is better - comparable to 2.4.18 in what I have seen with my script.

After the long obscure problems since 2.4.19x, -rc6 could use serious
stress-testing.

User level testing is not sufficient here - it's just like playing roulette.

By serious stress-testing I mean:

Everone testing comes up with one dedicated "tough test"
which _must_ be reproducible (program, script) along his line of
expertise/application.

Two or more of these independent tests are run in combination.

This method should increase the coverage drastically.
