-Subject: [PATCH] Revert "Remove priority from attribute
- constructor/destructor"
-
-This reverts commit 0340df46ec5897636dd071bc8b5c4272cfa7d7be.  It works
-around an irrelevant operating system and breaks compilation on Guix:
-
-mem.c:873: fatal error: RUNTIME_CHECK(((pthread_mutex_lock(((&contextslock))) == 0) ? 0 : 34) == 0) failed
