this is a noop in OCaml, but fixes the build in OxCaml (which infers stack allocation locality without an explicit annotation in the case of partial application)

There was a problem hiding this comment.
if we're eta-expanding i think we should also inline, very little point in defining the intermediary identifier
wrap_syscall Read ch (fun () -> if Sys.win32 then Unix.recv ch.fd buf pos len flags else stub_recv ch.fd buf pos len flags)
or maybe even better
else if Sys.win32 then
wrap_syscall Read ch (fun () -> Unix.recv ch.fd buf pos len flags)
else
wrap_syscall Read ch (fun () -> stubs_recv ch.fd buf pos len flags)
because it becomes very readable, easy to scan the two lines and spot the difference
