Ok, I'll look into that.

I'll probably benchmark a bit in iexplore in Wine before I remake the patch
with hg(1) and submit it to Mozilla bugzilla.

Thanks a lot.  It really fixed it.  I used it today with Wine 1.5.1 for a
BridgeCentral network database connection for 3½ hours without any crash. 
Without a fixed dll, it would have crashed within 9 minutes.
