        guile-core/libguile: ChangeLog __scm.h eval.c eval.h print.c 
                             pthread-threads.h snarf.h tags.h threads.c 
                             threads.h 

Log message:
        * __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.
        Simply lock a thread C API recursive mutex.
        (SCM_NONREC_CRITICAL_SECTION_START,
        SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
        SCM_REC_CRITICAL_SECTION_END): Removed.
        
        * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with
        direct calls to scm_rec_mutex_lock / unlock around the three calls
        to scm_m_expand_body.
        
        * eval.c, eval.h (promise_free): New function.
        (scm_force): Rewritten;  Now thread-safe; Removed
        SCM_DEFER/ALLOW_INTS.
        
        * pthread-threads.h: Added partially implemented plugin interface
        for recursive mutexes.  These are, for now, only intended to be
        used internally within the Guile implementation.
        
        * pthread-threads.c: New file.
        
        * threads.c: Conditionally #include "pthread-threads.c".
        
        * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be
        thread-safe;
        
        * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX,
        SCM_GLOBAL_REC_MUTEX): New macros.
        
        * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section
        macros---use mutexes instead.
        
        * tags.h (SCM_IM_FUTURE): New tag.
        
        * eval.c (scm_m_future): New primitive macro.
        (SCM_CEVAL): Support futures.
        (unmemocopy): Support unmemoization of futures.
        
        * print.c (scm_isymnames): Name of future isym.
