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.
