Hi! I had no issue with read/write concurency on any variable, but i cannot say they not exist. I may try to use a mutex like mechanism.
Regarding position reporting , I plan add buffer status to status reporting and feed movement related gcode only if at least two blocks are free in the buffer (there may be an aditional backlash block generated) so I do not block the serial.

I can say that I am checking your account multiple times per day, waiting for the new version :)
