Take into account the change in Rdbg.event w.r.t. event number (rdbg 1.51).
Also correct a lot of bugs. Indeed, this module was not tested when I initially wrote it, because of the sig faults pbs. Not that it is still not working properly, as the CPS transformation breaks Pascal's way of handling Lutin choice points backtracking, that is based on ocaml exception. Indeed consider this exemple: try call_to_a_func_that_traverse_the_lutin_FT () with Deadlock _ -> the_backtrack code now, if call_to_a_func_that_traverse_the_lutin_FT returns an event, the ocaml try is deleted !!!
