The process module could be improved in a number of ways.

It should be possible to use an arbitrary number of reader pipes, writer pipes, PTYs, socketpairs and other communication channels to a process. These communication channels should be freely assignable to any set of child filedescriptors.

It should be possible to somehow assign separate protocols for communication channels. For example, it should be possible to use NetstringReceiver for stdin/stdout and LineReceiver for stderr for the same process.

It should be possible specify a preexec function or a list of preexec functions to execute after forking but before execing the child. For example, this is useful for a combination of chroots and chdirs before execing the child.

Start with the process module and review the attached twisted-process-improvements.patch and twisted-process-improvements-2.patch to understand the proposed direction. The work is done when arbitrary communication channels can be assigned to child file descriptors, separate protocols can be used per channel, and preexec functions are supported as described.
