There is even a better solution for this, namely not to directly activate
the async for the after-gc-hook from the gc, but rather have a C hook
function registered in the scm_after_gc_c_hook which then activates the
async.  Thus, in the core of the gc there are only C level hooks.

The current cvs incorporates the necessary changes.  The benefit is a
cleaner separation of the async stuff from the gc core and a cleaner
separation of the scheme level stuff from the gc core.  The current
solution, however, does not yet add the additional C level hooks, but I am
going to provide this next.
