flock and sockets

[Daniel Luna]

I am planning a Haskell project and I need to access files. Since the
program will be automatically started whenever a mail comes in I will need
to be able to lock the access to files. Is there any support for this in
some library?

The second option that I have is to use a daemon and let the programs that
get started by mail connect via some sort of socket. Is there any socket
support in Haskell?
