alt Hacker NewsWhat are some of the other problems with rwlocks? I genuinely ask because I used them with quite good success for pretty complicated use-case at large scale and very high concurrency.

I have as well. I find RW locks much easier to use than, say, a recursive mutex. Mainly since it took me a long time to actually understand how a recursive mutex actually works in the first place. When you want to use only the stdlib, you aren't left with many choices. At least in the STL.
Mostly that if you actually have both readers and writers, they obstruct each other; this is often undesirable. And you have to pick some bias in advance. You can get priority inversion because readers are anonymous.
