This is not possible with some of the functions, for which there's no
way of checking for a resource without blocking.

In addition, if an application wants to issue a low-level system call,
the library has no business interfering with it.

There are functions that by definition always wait for something.  These 
functions *should* call __dpmi_yield.  However, I think most, if not all,
such functions already do that.

So what you suggest is not always possible or desirable.  But if you
think that there are some library functions which should do this but
don't in the current version, please feel free to submit bug reports
and/or patches.
