01:18	*	asciilifeform 'enjoying' the wunderful world of 'write one-writer-many-readers mutex from thin air'
01:19	asciilifeform	( cpp14 included one, but 11 -- not. and sane gcc is perma-fossilized on 11... )
01:20	*	asciilifeform thinks 'maybe cribbable from 14's stdlib?'
01:21	asciilifeform	prolly not portably tho, likely soup of x64 asm.
		~ 8 hours 58 minutes ~
10:20	awt	http://logs.bitdash.io/pest/2022-12-25#1019414 << If you want a patch I can produce it.
10:20	bitbot	Logged on 2022-12-25 22:07:13 asciilifeform[jonsykkel\|awt\|deedbot]: phf: atm even that 'send erryone a % command to run' lolbug still standing
		~ 34 minutes ~
10:54	asciilifeform	awt: would be great, if you've the cycles, ty
		~ 5 hours 59 minutes ~
16:54	phf	http://logs.nosuchlabs.com/log/pest/2022-12-26#1019498 << `he now has two problems`

		~ 45 minutes ~
17:40	asciilifeform	phf: went and rtfm'd, and is even worse than at 1st thought ( found wai committee did not include in -11. r-w locks apparently weigh enuff so as to make spinlocking look good in comparison..)
17:41	*	asciilifeform for many many yrs dodged the draft of having to giveashit about locks, semaphores, etc. and nao having to reload into head
17:44	asciilifeform	orthogonally -- asciilifeform suspects that his algo from earlier is actually braindamaged. tick() oughtn't be called at 1hz by a thread, oughta be triggered intelligently on a write if the latter happened 1s <= t <= maxticks, per timer, after last write;
17:45	asciilifeform	and then purge by tick() floor(t) times.
17:45	asciilifeform	( on read ditto )
17:46	asciilifeform	still not gives parallelistic lookup tho. for that, sumthing like rw lock not escapable afaik.
17:50	phf	tick is essentially gc phase, if you do `smart trigger` you end up with hidden and random `gc phase`. milage may vary
		~ 1 hours 7 minutes ~
18:57	asciilifeform	phf: also tru
18:57	*	asciilifeform leaning in direction of mechanical simplicity, 'optimize laters'
