Bump version number to 0.11.1
Modify the behavior of chos_do_fork to explicitly set the CHOS link of
new processes to match that of the parent process.

do_fork() copies the original process, wakes up the new process, and
then returns.  This means that there is some amount of time where the
new process is awake but the real do_fork() has not yet returned.
This change should eliminate some scenarios where the child process
forks its own child process and then exits before its CHOS link is
set, resulting in the newest child process not receiving the correct
CHOS link mapping.
