[IronPython] thread.interrupt_main() not implemented

And we implement that using Thread.Abort (which is the only way we really have to interrupt a thread at an arbitrary point in time) :)  When the user catches it they'll see it as a KeyboardInterruptException, and we'll do the right thing for Thread.ResetAbort().

If you want to get the exact behavior we cause with Ctrl-C it's actually:

import clr
from Microsoft.Scripting.Shell import KeyboardInterruptException

in v1.x it's:

import clr
from IronPython.Runtime.Exceptions import PythonKeyboardInterruptException

and then the user can catch it as a they'd catch a normal keyboard interrupt.  I think the only reason we don't have this implemented by default is that in some situations (e.g. outside the console) we won't actually know what the "main" thread is.

thread.interrupt_main has somewhat different semantics than Thread.Abort; it basically triggers a keyboard interrupt on the main thread -- this is, of course, an exception that can be caught and handled by user code on that thread.

I think you could work around this by remembering the main .NET thread and calling Abort on it:

from System import Threading

main = Thread.CurrentThread

# and then later on...


But I'd suggest that interrupting a thread at an arbitrary point is a little dangerous (as it may have some state which isn't entirely consistent that it's trying to update).

When i want to use thread.interrupt_main() in iron python script, i've got this error:
   NotImplementedError: interrupt_main not implemented

Is there an equivalent in ironpython?
