That's maybe too complex for now, this patch (on top of existing
sleepy GC):
https://80x24.org/spew/20180514201509.28069-1-e@80x24.org/raw
While the effect on big Rails apps seems minimal, I think the
significant improvements for small scripts is still helpful and
we can build on top of them. I am already satisfied with the
improvement from a Net::HTTP example from the first patch:
https://80x24.org/spew/20180501080844.22751-3-e@80x24.org/raw
Since all new behavior changes can be easily disabled via gc.h,
I propose we commit the current changes to trunk for now to
gain more testing and feedback.
Current series is up to 8 patches, but I will squash
"thread_sync.c (mutex_lock): add missing else" into
"thread.c: native_sleep callers may perform GC".
The following changes since commit 6f0de6ed98e669e915455569fb4dae9022cb47b8:
error.c: check redefined backtrace result (2018-05-14 08:33:14 +0000)
