* __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
(SCM_ALLOW_INTS): Added thread switching code before interrupts
get re-enabled. The important effect of this is that interrupts
are blocked during thread switching so that thread data structures
don't risk getting messed up by an unfortunate signal.
(SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
seems to do more aggressive optimization which actually move
instructions around in these macros in a fatal way. Therefore:
Introduce Anthony's SCM_FENCE macro! (And I who thought he was
just superstitious...)
(SCM_TICK): Maybe do a context switch and take care of asyncs.
This macro should be used instead of SCM_ASYNC_TICK since the
latter doesn't do context switches any more.
