Thanks for the extra detail.  I'm convinced now.

I know I must have understood all this code once, because I changed
this stuff for 2.6 and got rid of the per-export-entry 'host's and
just kept per-ip-address hosts.  The actual patch can be found at:

http://www.cse.unsw.edu.au/~neilb/patches/linux-devel/2.5.34/patch-F-LockdSeparate

I hope it's right :-)

I'll submit your patch for 2.4.23.
