Gosh!  I noticed that the mutex code in gmalloc.c did not take effect
at all because `HAVE_GTK_AND_PTHREAD' is checked before including
config.h.  Could you try moving the following part at the beginning of
gmalloc.c to just before the first occurrence of '#ifdef USE_PTHREAD'?

#ifdef HAVE_GTK_AND_PTHREAD
#define USE_PTHREAD
#endif
