I assume that you use some preemptive RTOS, if not then locking (at the 
libc level) doesn't matter.

If the avr-libc tends to be similiar to "standard" libc (more or less 
POSIX like) then there are well defined rules and interfaces for thread 
safe functionality. IMO there is no need to invent something new.
It will be very interesting (and ambitious) project to extend the 
avr-libc in such way.
Do you want start it 8-)
