the problem is just over-complication of existing Handle
implementation - it's about 2kloc of high-messed code. taking into
account that it lacks a lot of other required features, it's quite
meaningless to spend a lot of time fixing it for just one particular
problem

i've implemented 2 versions of Streams library which includes
everything i know about i/o (i.e. no networking, overlapped i/o or
iconv) and started to implement its 3rd version which includes
bytestring i/o but then switched to more interesting project. Streams
is still the most complete haskell i/o library and quite useful. its
main drawback is lack of docs, especially for second version, but to
some degree you can understand it just by analogy with System.IO
interfaces
