| Further, managing thread-local-storage lifetime is a lot more problematic when slots can be freed and reused. (actually a lot of ppl think this is why musl doesn't unload libraries, which isn't the case. it's possible to do right, just more work). | ||
| On glibc this actually makes for some weird race conditions where a library that 'could be' unloaded doesn't get unloaded, and unloading it either never happens or gets deferred to the next dlclose operation - which breaks anything assuming that dlclose will actually unload. | ||
| So programs making this assumption are already broken on glibc too, just with random rare failures rather than failure every time. | ||

Generally I think it would be nice to keep the formatting/wrapping like the other answers.

the others are formatted to 80 chars line length, tho md rendering disregards newlines anyway - and as this faq is not meant to be read in a terminal i opted for the quick way...

If you use vim, just select the whole block and gq it. It will auto format the whole thing.
