Waits like the OpenMP runtimes: bounded poll spin, yields, then sleep; wait benchmarks (faer#107) by shinaoka · Pull Request #14 · tensor4all/threadteam-rs

waits: staged like the OpenMP runtimes (bounded poll spin, yields, then sleep) for members, joins and barriers; scheduling pressure throttles (faer#107)

waits: libgomp-like default budget (131072 polls, ~3 ms), pool throttle only on repeated preemptions; wait counters and an interleaved A/B script

waits: a preemption throttles the thread that saw it, not the pool; fresh-pool phases in the bench

waits: back to the pool threshold (c0c024b) as the default, per-thread hold as a knob; libgomp held team and load in the A/B runs

waits: spin 300000 polls (GOMP_SPINCOUNT) by default; a knob to turn preemption detection off for the libgomp-like comparison

waits: libgomp's waits by default (no preemption detection, spin 300000); detection and the pool throttle only during a new pool's warm-up (200 ms)
