This fixes issues found in e066f35c6981c720e3a7e5883efc40c861b3b7, which was later reverted. The problem was with "k" message which was sent with sync_on_timeout flag set to true, so lldb was waiting for response, which is currently not being sent by lldb-server. Not waiting for response at all seems to be not a solution, because on MAC OS X lldb waits for response from "k" to gracefully kill inferior.
