calling handlers within R_tryEval

Hello,

When using R_tryEval (from JRI in my case), is there a way to setup error 
recovery strategy and more generally calling handlers.
From my reading of context.c, R_tryEval calls R_ToplevelExec which creates a 
context like this:

  begincontext(&thiscontext, CTXT_TOPLEVEL, R_NilValue, R_GlobalEnv,
       R_BaseEnv, R_NilValue, R_NilValue);

so I guess what I am trying to do is add "cend" and/or "handlerstack" to this 
context. Is this possible ? Are there examples of packages doing this ?

Not at present.  It would be nice to have at least a mechanism for C
level exiting handlers (which is what the cend ones are intended to be)
but it hasn't risen high enough on my to do list yet to get done.
