The Terminal program in OS X has recently[1] acquired separate bash 
history files for separate sessions.  These live in the directory
~/.bash_sessions.

I'll admit I haven't explored this feature in depth yet, but when
running Terminal with multiple sessions open, close then restart it
(usually only done here for a logout/login or reboot), then each
session has its previous context for current directory and history
restored.

(The scrollback buffer for each session in also restored, but that's
probably part of the general OS X support for restoring application
context from the previous session.)

[1] I _think_ this feature arrived with the latest major version
of OS X, last autumn.
