Sam, have you looked into this? jemalloc seems to use _SPINLOCK in some cases,
depending on how the defines are set up, short grep:
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c-#else
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c:static
malloc_mutex_t init_lock = {_SPINLOCK_INITIALIZER};
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c-#endif
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c-
--
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c-
return (true);
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c-#elif
defined(MOZ_MEMORY_DARWIN)
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c: mutex->lock =
OS_SPINLOCK_INIT;
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c-#elif
defined(MOZ_MEMORY_LINUX) && !defined(MOZ_MEMORY_ANDROID)
./www/firefox/work/mozilla-release/memory/jemalloc/jemalloc.c-
pthread_mutexattr_t attr;

So in principle it shouldn't be too hard to get it to work. I'll have a look
myself tonight and see what can be done, but maybe you've already made some
progress on this?
Cheers,
