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)
