RA_YIELD 1.0 => Implements '_appl_yield' for MultiTOS AES
----- why you may need RA_YIELD -----
It is needed for using STinG (all versions) under MTOS AES 4.1.
It is also very helpful in making MTOS AES 4.0 more efficient.
It may have similar effects under other MiNT-based multitaskers.
Under non-MiNT systems it will ensure that '_appl_yield' overhead
costs occur at most once per two system clock 'ticks', which is
10 milliseconds.  That should make the costs negligible.
But RA_YIELD should not really be needed under any systems that
have a fully functional '_appl_yield' function. (MTOS does not!)
----- installation -----
RA_YIELD must be installed after the new AES has been loaded, so
for MTOS the correct way to do it is by a 'run' line in GEM.CNF
eg:  "run c:\mint\ra_yield.prg"
You can store the program anywhere, as the 'run' commands of GEM.CNF
need full paths anyway.  Just be sure you specify it properly.
----- technical -----
RA_YIELD links into the BIOS and XGEM vectors using the XBRA id
"RAay" (Stands for "Ronald Anderssons _appl_yield"), and it has
special protection against some programs that can trash the XGEM
XBRA chain (such as NVDI).
----- legal -----
RA_YIELD was created by me, Ulf Ronald Andersson, and I reserve
all rights to it, but I also release it as FREEWARE for unlimited
use and distribution. So it is free, and I own the right to say so.
----- version -----
This is version 1.0, the first public release of RA_YIELD.
It was assembled on 1999.06.17  (June 17 1999).
