Comment:

 I believe the above patch fixes this ticket, because you can now just
 throw an exception to the thread that calls `runStmt` and the right thing
 will happen: `runStmt` will return with `RunException e` where `e` is the
 exception you threw.

 {{{
 Author: Simon Marlow

 Redirect asynchronous exceptions to the sandbox thread in runStmt
 (#1381)

 See comment for details.

 We no longer use pushInterruptTargetThread/popInterruptTargetThread,
 so these could go away in due course.

New description:

 Hi

 I would like an extension to the "GHC as a library" API, so that if I have
 done:
 {{{
   runStmt someStatement
 }}}
 I can prematurely terminate the execution.

 I have posted this request on ghc-us...@haskell.org and a more thorough
 explanation can be found there: http://www.haskell.org/pipermail/glasgow-
 haskell-users/2007-May/012613.html


 Greetings,

 Mads Lindstrøm

 I'm not familiar with the details, but it sounds as if you are any
 chance of a patch?

Comment(by edsko):

 There is currently no good workaround for this, because
 `Panic.interruptTargetThread` is not exported, and hence we cannot find
 the `ThreadId` of the thread spawned by `runStmt`. We can avoid `runStmt`
 spawning a thread at all by disabling `Opt_GhciSandbox` so that we can
 throw `UserInterrupt` to the thread that calls `runStmt`, but that means
 that the debugging facilities don't work anymore.
