A comment in src/lib/libc/stdlib/malloc.c (FreeBSD Current) says:
/*
* Mutexes based on spinlocks. We can't use normal pthread mutexes, because
* they require malloc()ed memory.
*/
So it seems to be impossible to make src/gmalloc.c thread-safe only
using pthread mutexes.
I'm not sure if spinlocks are open to user applications, but anyway it
would be simpler to define SYSTEM_MALLOC when HAVE_GTK_AND_PTHREAD &&
!DOUG_LEA_MALLOC, and abandon emacs_blocked_malloc etc. on such
platforms. I don't care if my changes made to src/gmalloc.c for
thread-safety is reverted.
