Does disabling Stacktrace resolve the problem?

And what about completely disabling the dbghelp initalization?
I think commenting out the import would suffice.

Are they over 4 seconds like they were for me before I switched?

I have a small benchmark for exceptions, and they are much much slower than
equivalent exceptions in Java.

Ok, but is it a regression from an earlier release? We should mark this as a
normal bug if not to avoid blocking the 2.063 release (I personally can't
recreate the huge slowness anymore).

I think this bug should not block 2.063, because probably will require a fair
amount of work to be fixed, and the situation is probably not a regression any
more.

If someone has had their exceptions slow down significantly since 2.053, re-set
it as a regression. But I'm lowering it to normal for now.
