regression - fails to load on ABCL

[avodonosov]

Since quicklisp 2014-07-14 datafly fails to load on ABCL: http://common-lisp.net/project/cl-test-grid/library/datafly.html

The error is

SIMPLE-TYPE-ERROR : The value of BORDEAUX-THREADS::LOCK is #S(BORDEAUX-THREADS::MUTEX :NAME "Anonymous lock" :LOCK #<java.util.concurrent.locks.ReentrantLock java.util.concurrent.locks.Reent.... {1A11FBF}>), which is not of type BORDEAUX-THREADS::MUTEX-RECURSIVE.

Sorry I found time to report it only now.
