What
The event-loop stall detector now measures elapsed time with a monotonic clock as well as the wall clock, so a system clock jump is no longer reported as a stall.
Details
- New reported fields: monotonic stall duration, clock jump, whether a slow terminal write was blocking, and whether a resume signal (SIGCONT) was seen, meaning the machine had been suspended.
- Reporting is deferred to the next tick so measuring the stall does not lengthen it.
- Runs whenever the detector is started.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
