Comment(by mevenson):

As far as I understand a quick analysis of SBCL which is also a multi- threaded Lisp, to implement this we would have to:

1. create a global mutex WITH-PACKAGES for FIND-PACKAGE, MAKE-PACKAGE, RENAME-PACKAGE, DELETE-PACKAGE, LIST-ALL-PACKAGES, INTERN, UNINTERN, EXPORT, UNEXPORT, IMPORT, SHADOWING-IMPORT, SHADOW, USE-PACKAGE, UNUSE- PACKAGE, and FIND-ALL-SYMBOLS.

2. Check that nicknames are not being used as the redefined name (??)

3. Warn about various changes (like unusing previously used packages)
