[slime-devel] Trapping the Emacs interrupt conditions from user code

I would like to be able to have the user code trap the "Emacs interrupts", which are
currently being raised by Swank as SIMPLE-ERRORs.

I have defined a USER-INTERRUPT condition which subclasses SIMPLE-ERROR in Swank code,
and made it throw that instead.

But, somewhat predictably, trapping SWANK::USER-INTERRUPT from user code did not work,
because it seemingly runs the user code in a different thread from the one raising
the condition (i.e. the main Swank thread?).

So, the question is, what would be the way to get that which i want with little-to-none
injury? (And would such an enhancement be considered useful for Swank in general?)
