There is an effort to move some GHC-specific modules out of
base. Candidates for such moving areGHC.IO.Handle.TypesandGHC.IO.Handle.Internals. These modules are often used for obtaining POSIX file descriptors from Haskell handles. Such a use is also present in thesendfilepackage in the implementation of thewithFdoperation.There is a proposal to add dedicated operations for operating-system handle acquisition to
base. A corresponding draft implementation can be found in GHC merge request !14732. The present pull request changes the implementation ofwithFdto use one of those new operations.
