I slightly tried more with t226.rb failure,
it is timing dependent, the problem is
at the end in thread.join.
Might be bug in design of system pthread library,
too much optimizing compiler or bug in ruby thread library.
The ruby1.8_1.8.7.174-2, compiled on Aug 19 passes
the same test repeatedly fine.
