This is something I have already asked. It seems this is not possible 
currently. Something like ?addTaskCallback, but registering an R 
function that is to be called *before* a top-level task is run would be 
wonderful (???addTaskStart).
Best,

P.S.: this would solve also another problem we have for some GUIs: to 
know if R is busy processing commands issued at the command line or not 
(just set a busy flag to TRUE with a function registered with 
"addTaskStart", and set it to FALSE with a function registered with 
addTaskCallback). Of course, a R function that provides this information 
more directly would be much, much better.
