Log:
Refactor tracing mechanism to be less intrusive; specifically, don't
install a global trace hook if one's already in place, don't uninstall
it if we didn't install it, and make sure that uninstallations happen
in the correct chaining order.  This may fix some long-standing issues
with debuggers (such as PyDev) that use different local and global 
tracing functions.
