Hi,

I vaguely remember that the problem was a defiency of the early 
versions of Tk (you know, back in the 4.x versions). Of course, it 
would now make sense to have a better interface to the Tcl FileHandler 
API.
We could have a camltk_createfilehandler and camltk_deletefilehandler 
mirroring the Tcl API, allowing for the TCL_READABLE and TCL_WRITEABLE 
flags, with backward compatibility for the old API implemented with the 
new one (e.g. add_file_input would call createhandler with 
TCL_READABLE).
Seems possible.
Anyone has the time to write a patch ;-) ?
