Ok, seems reasonable ;-)

Does it mean that sit-for will have to do active wait [1] ? I think
it's not a good way to go, or have we an alternative?

In a first place, I thought that `read-char' could store the var from
which the char read has been taken, so that a function `putback-char'
could but it back in the good list.  How about that ?

However,  I've   always  dreamt  about  an  unique   entry  point  for
unread-events: unread-command-events would  store direct events (u-c-e
= '(?a ?b))  or events as a cons, the cdr  telling if input-method has
to be used (u-c-e = '(?a (?b . nil) ?c)). Does it seems crazy? [2]
