Proposal: ByteString based datagram communication (Ticket

I'm back and am keen to work on getting this patch accepted.
Concerns I've so far seen raised include
1. bos: It breaks the existing stable API
I need more information on this; I can't see what's broken unless the
change of sendTo and recvFrom to datagram functions is what is
considered broken. I'd argue the current sendTo and recvFrom
functionality fits their names. This patch fixes that.
2. bos: It restricts to AF_INET
As far as my testing has shown it should also work with AF_UNIX. To
get it working with AF_UNIX the patch also includes a bugfix in
Network.Socket. As such, the patch should hopefully reduce the
current AF_INET restriction.
3. dons: Similar work has been done on HAppS and HaskellNet
I'm keen to integrate any ideas from these platforms. I'm discussing
it with S. Alexander Jacobson. If anyone can outline some good ideas
from these platforms that should be included in the patch I'll gladly
look into it. However, It's meant to be a simple change to make
sendTo and recvFrom act as expected of network utilities with those
names while providing convenient and efficient datagram utilities
similar to what exists for stream based connections rather than add
too many features.
4. me: It's not tested as well as I'd like
I'm having trouble testing with hugs. runhugs -98 ./Setup.hs build
returns 'ERROR "dist/build/Network/BSD.hs" - Can't find imported
module "GHC.IOBase"'. Something screwy with hsc2hs or cpphs?
I don't have windows so still haven't tested that. Can any Windows
users help please?
