fold happens over `unpackBytes` instead, which generates list in small chunks that can be processed lazily. This looks like a `bytestring` bug to me. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7556#comment:2> GHC <http://

O using threads, and that's much nicer. But before we do that, we should look at how people are using these APIs. The only user of `hGetBufSome` that I know of, lazy bytestring, works just fine with the "read a random amount of data" semantics. -- Ticket URL: <http://ha

Re: [GHC] #4144: Exception: ToDo: hGetBuf - when using custom handle infrastructure

nds right now, hGetBuf, hGetBufNonBlocking and hGetBufSome will all read the same amount of data, if the data is available without blocking. I don't think this is the case anymore; see #5843 and commit [https://github.com/ghc/packages- base/commit/370fc0b455f6a03283fbd5c0baa5d08d9115379d
