Attached is a module containing ByteString analogs of two functions from System.Process: readProcess and readProcessWithExitCode. I use these a

and would love to see them incorporated into a standard library, though I'm not sure which one.

Sorry, didn't know attachments were excluded. The two functions are available in the Unixutils library:

Some time ago I fixed some asynchronous exception bugs in those functions. Take a look at the current implementation:

You might want to incorporate these changes into your library.

It looks like this will have to wait for bytestring 0.10, which has NFData instances. I guess there are ways to hack this...
