Long pauses while single stepping

While debugging with breakpoints and single stepping, about 1 in 10 steps results in a long pause (as if it were waiting on a timeout). The pause can be as long 10 secs. The pause also happens after some exceptions, even handled exceptions. This occurs on TinyCLR 2.0, but I did happen on 1.0 but less frequently.

Is this a Visual studio issue ?

No it is on our end and we are looking into the issue.
