hi!
i've got a macro that i need for debugging code and i think it would be useful for b-t. it's called with-thread-name, that appends the given string to the thread's name and restores the old name in an unwind-protect.
it's useful when you have 10 nodes with 25 threads each and need to debug stuff like sbcl hanging in CLOSE on a socket.
if you like the idea i can move it into b-t and package up as a darcs patch.
