I think `_sleep' etc. should be kept but `sleep' etc. should be removed.
I am also wondering whether we should add a UNIX-like `sleep'. This idea
is attractive, and some Win32 compilers (like Digital Mars) already
provides such a function (but DMC does not provide `_sleep'). However,
if (old) MSVC compatibility is to be kept, and `_sleep' is to be
retained, then a `sleep' having different semantics from `_sleep' might
be confusing. So....
