    Hold the GC lock when traversing weak hash table buckets.
    
    Initial attempt to fix the segfault with this program:
    
      (use-modules (ice-9 threads))
    
      (call-with-new-thread (lambda () (while #t (gc))) (lambda () #f))
    
      (let ((h (make-doubly-weak-hash-table 0))
        (the-key (cons 'the 'key)))
        (while #t
          (hashq-set! h the-key (list 1))
          (assq-set! (hashq-ref h the-key '()) 'akey (list 1))
          (display ".")))
