charset="utf-8" It's true that these functions currently affect the batch size in which coroutines are reused (i.e. moved from the global release pool to the allocation pool of a specific thread), but this is a bug and will be fixed in a separate patch. In fact, the comment in the header file already just promises that it influences the pool size, so reflect this in the name of the functions. As a nice side effect, the shorter function name makes some line wrapping unnecessary.
