evaluator-break during instantiation
Apparently evaluator-break doesn't work when instantiating a module.
Of course you can't! I'm confusing two things here. The evaluator
isn't yet defined so you can't send it anything..
What i want is to be able to break instantiation.
Say you have a module which takes a while to instantiate using
"make-module-evaluator" from scheme/sandbox. How would you
make it possible to interrupt the instantiation? Obviously
"kill-evaluator" or "break-evaluator" won't work yet since there is no
value to apply them to, and other attempts to kill it seem to fail:
(define e #f)
'(module foo scheme/base (let x () (x))))))))
# (kill-thread t)
kill-thread: the current custodian does not solely manage the specified thread: #<thread>
This seems to leave the instantiation still running in the
background (judging from "top").
# (break-thread t)
However, hitting ctrl-c when evaluating the following does seem to
stop the instantiation.
# (make-module-evaluator '(module foo scheme/base (let x () (x))))
