This is discussed in the Allegro CL User Guide, page 3-25, volume 1.
In short, you can disable package locking, though it is strongly
discouraged.  You would not believe how many sprs we had because
people did this:

	(defstruct instance ...)

which obviously clashes with make-instance if package locking is not
enabled.

Also, there is a typo in the User Guide: the variable
excl:*enable-package-lock-errors* is really
excl:*enable-package-locked-errors*.
