Comment (by rwbarton):

 I don't think this is a big deal, but `throwErrnoIfRetryMayBlock` isn't
 getting inlined. It probably should get inlined.

 Also, there is a safe foreign import of `rtsSupportsBoundThreads` in
 GHC.IO.FD (and also some other module(s) in base), which seems quite
 unnecessary considering `rtsSupportsBoundThreads` simply returns a
 constant.
