[RhinoCommon] Curve.OffsetOnSurface prints "Press Esc to cancel" on command prompt

As per title. Everytime I run OffsetOnSurface on a curve I get this message.

I have been experiencing the same issue since the last few service releases.
Seems like this bug is not high priority one, as the method actually works.

Ok, well as long as McNeel is aware of the problem.

The core calculation runs in a cancel-able worker thread. Our worker threads always print “Press Esc to cancel.”
