Parrot 1.8.0: Calls for updates to NEWS, PLATFORMS and CREDITS

Howdy,

Yes, I have been busy lately and have not had time to work more on
Parrot+RTEMS. My initial blog post [0] is a reasonably accurate status
update for where we are now.

In short summary, Parrot 1.8.0 will not ship with RTEMS-support out of
the box. Parrot has had patches applied to it that make
cross-compiling Parrot to RTEMS possible, but we are still working to
make the build system do this automagically. I think the RTEMS people
plan to provide some packages that will ease running Parrot on RTEMS,
but I am a little fuzzy on this right now.

Parrot works on RTEMS. I am not sure how our garbage collector
interacts with the real-time-ness of RTEMS, though. It may need to be
shut off currently, to retain realtime characteristics. I have been
doing research on realtime gc algorithms, there are a few implemented
on the JVM [1], JeRTY VM [2] and Jikes RVM [3]. The "Tortured History
of Real-Time Garbage Collectors" also seems like an interesting read.
