Actually, the succss of this project is highly dependent upon how
restartable scm_async_click is.  ;-)

My guess is that it would "sort of" work, but this is also code which
needs revision.

(Actually, scm_async_click should be removed.  SCM_ASYNC_TICK should
 be redefined *only* to deal with asyncs.)
