The same happens (at a lower rate) with Cocoa. After a minute of idle  
texmacs I get the following  (4kb of 16 byte blocks allocated in the  
meanwhile):

I do not understand why this does not happen in X11. Maybe the way we  
call the interpose_handler?
Can you explain me which part of the guile code is calling  
tmg_texmacs_time ?
