* src/xgselect.c (release_select_lock, acquire_select_lock): Introduce. (xg_select): Use `acquire_select_lock', `release_select_lock'. * src/thread.c (release_select_lock): Introduce for non-GLib builds. (really_call_select): Call `release_select_lock'. Simplify by ensuring acquisition of the lock always succeeds (bug#36609).
