Nope, because emacsclient ends up opening them all in the same process (that's the beauty/entire point): Fork off an emacs in the background:
emacs --daemon
Then run emacsclient to connect to it (open a new buffer in the daemon and switch to it):
emacsclient -nw some_file
When you "quit" (with C-x C-c), it really just quits that client, but the main emacs is left running.
This has a number of benefits: 1) no locks like you mention, 2) access to all open buffers (even unsaved) from every emacsclient that's currently running (since they're really all just opening buffers in a single instance), 3) blazing startup speed (emacs is already running, you're just connecting to it and splatting a new buffer to the terminal).
