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.
