Revision - 65d5762 - improve yieldto error handling

Revision 65d5762485dfdc3d57f8463ba1852d6526019c70 authored by Jameson Nash on 20 April 2017, 18:42:56 UTC, committed by Jameson Nash on 22 April 2017, 18:58:09 UTC

improve yieldto error handling

previously we couldn't reliably tell the difference between a failure to context switch
and an explicitly scheduled error

in the former case, we often need to undo some prior action
by moving the code for the later into Julia,
we can reliably run the necessary undo action when required

fix #21442
