What's Changed
- Fix urllib3 pools with
block=True, e.g. a requests session withHTTPAdapter(pool_block=True), waiting forever for a free connection in a cassette, or when used before, after or across cassettes. A response now returns its connection to the pool once its body has been read, as in urllib3, and vcrpy keeps a pool's free slots when it takes connections out of it as a cassette starts or stops using the pool. A response finished after its cassette has exited gives back only the slot, not the cassette's connection (#949, #1094) - thanks @nk-batman21
