It looks like Igor comitted it to the 4.1 tree on the 2nd of this month:

ChangeSet
  1.1553 03/08/02 02:43:18 [EMAIL PROTECTED] +43 -0
  Many files:
    Added key cache assignment
  mi_locking.c:
    Added key cache assignment: correction
  my_sys.h:
    Added key cache variable structure

Monty hasn't done the code review of any of the recent commits to 4.1
(he's almost finished with 4.0 it looks like) yet, so my guess is this
should be going into 4.1.1.
