So far I have refrained from adding Lua to the kernel side for
debug/message logging (under LynxOS). It would require thread/interrupt
synchronization. This can be solved, of course, despite the possible
garbage collection issues. But I have found that having interrupts
disabled for the short period of time it takes to check an integer value
and write a small record to the end of a FIFO provides enough
flexibility that I do not need anything more elaborate on the kernel side.

But I do use Lua in my logger daemon in order to get/set debug levels
for registered drivers. I used Lua to avoid the necessity of writing a
command interface. It has been unchanged for a long time now - I never
did get around to more complex reading/selection when pulling messages
out of the FIFO. I haven't really needed it.

I will be interested to see what you come up with.
