Hello,

Test done on Ubuntu 15.10.

On latest master, 7cd835177ae  while trying to build core-image-* the environment stalls when pressing Ctrl+C during parsing recipes stage:
cosscat@ubnt:/media/yp_builds/poky/build$ MACHINE=genericx86-64 bitbake core-image-sato-sdk 
Parsing recipes:  60% |######################################################################################################                                                                  | ETA:  00:00:05
Keyboard Interrupt, closing down...

ERROR: Timeout while attempting to communicate with bitbake server

the only way to stop it is by killing the resulted processes:
cosscat@ubnt:~$ for i in $(ps -eaf | grep bitbake | awk '{print $2}'); do  kill -9 $i; done



For an older commit, 34e95b034904 it used to work fine.
cosscat@ubnt:/media/yp_builds/poky/build$ bitbake core-image-sato
