merge revision(s) 33296:
* test/-ext-/old_thread_select/test_old_thread_select.rb: select() with timeout may return early in old Linux kernels with 250 Hz tickrate and no dynticks, so skip everything older than 2.6.32 (which has long term support). And, Make the timing assertions consistently use assert_operator with timing difference in error message Patch by Eric Wong.
