Prior to this, eventat(-1) would return the next-to-last event causing the back button to cycle back to the end of an event source instead of stopping at the start. r272757 Add schedgraph traces for callout handlers. Specifically, a callwheel logs a running event each time it executes a callout function. The event includes the function pointer, argument, and whether or not it was run from hardware interrupt context. The callwheel is marked idle when each handler completes. This effectively logs the duration of each callout routine in the graph. r274091 Bind Ctrl-Q as a global hotkey to exit. Bind Ctrl-W as a hotkey to close dialogs. r274902 Add a new thread state "spinning" to schedgraph and add tracepoints at the start and stop of spinning waits in lock primitives.
