by other low-level libraries, like collate.  Extra care has been given to optimize the performance
of normalizing to NFD, as this is what will be used by the collator.  The overhead of checking
whether a string is normalized vs simply decomposing a string is neglible.  Assuming that most
strings are in the FCD form, this iterator can be used to decompose strings and normalize with
minimal overhead.

The alternative is to record enough information that the
trap handler know which registers contain cached globals
and can flush the registers back to their original locations.
That's significantly more work.

This only affects globals that have been written to.
Code that reads from a global should continue to registerize
as well as before.

the installer adds go\bin to the system PATH now,
the output package names are in line with the linux

sane way, readme cleanup.

someone else could give it a try. See the readme

My theory is that the call to f() allocates, which triggers
a garbage collection, which itself may do some allocation,
which is being counted.  Running a garbage collection
before starting the test should avoid this problem.
