* thread.c (thread_start_func_2): don't interrupt when last thread exit
unless main thread is already exited. Otherwise main thread could be wrongly interrupted when it uses rb_thread_call_without_gvl(). Patch by Takehiro Kubo. [Bug #11237][ruby-dev:49044][GH-898] * test/-ext-/gvl/test_last_thread.rb: new test for the above fix. * ext/-test-/gvl/call_without_gvl/call_without_gvl.c: new ext for the above test. * ext/-test-/gvl/call_without_gvl/extconf.rb: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50900 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
