[LITMUS^RT] Budget Consumed By Jobs In Ready Queue

[Jeremy Erickson]

The patch does fix the bug.  I should point out that Jonathan's solution
also does fix the bug as well - that's the solution you explain as more
complicated (requiring changes in multiple plugins), correct?

My testing method was to use a task system/scheduler combination (with some
modifications I made to G-EDF) that consistently triggers the bug without
either of the patches, and running it numerous times.  It's the same system
that led me to discover the bug in the first place.  I do know that vanilla
GSN-EDF (pre-patches) also triggers the bug, but it does so much less
reliably.
