Not yet. According to the debugging tools there is indeed a steady  
growth of the allocated memory event in idle state (at much lower rate  
than previously) but I cannot trace it back to the qt code. Apparently  
the problematic allocations come from the interpose handles  
(specifically from the call to the function tmg_texmacs_time), are  
small blocks of 16 bytes which get never released. This does not  
happens under X11, but I do not still understand why.
