Ack; that should be easy to do. Nevertheless, please do look at patch 4/4 and say if you would prefer that approach. Do you happen to know if there's a testcase that exercises THREAD_GSCOPE_WAIT ()? Even simple programs evidently use THREAD_GSCOPE_SET_FLAG () / THREAD_GSCOPE_RESET_FLAG (), but I so far haven't been able to construct a program that would trigger the WAIT. I've tried dlopening and dlclosing libraries concurrently from several threads; I will try dlopening hundreds of libraries next (to hopefully trigger a reallocation of some table), but it would be handy if there was an official ready-to-use testcase.
