Description
(fd-peek handle amount) → (or/c string? eof)
handle : handle?
amount : (or/c integer? eof 'avail)
I hope that the handle can also be peeked. Unlike fd-read, which consumes data, it retains the data and can be read/peek next time.
I don't know if this makes sense, if I got anything wrong, please correct me.
Thank you for your consideration!

Research direction
Start by reading the existing fd-read procedure and the handle behavior it uses; the issue does not name implementation files or tests. Determine whether fd-peek can retain data without changing fd-read semantics, then verify that repeated reads or peeks observe the retained data and that amount values, including eof and 'avail, behave as specified.
