Right.  Your program's been stopped just mm from its real exit.

That won't go anywhere.  The remote end will need to be modified so that 
_exit causes the target to report back a program-exited packet (Wnn, see 
Remote Protocol in the doco).  It appears at present _exit is simply 
implemented as an infinite loop..
