Thanks for the tip, I will try it next time.

The problem was initially discovered back in 2003 (must have been with
4.8 or 4.9) and after switching back to fxp I haven't tested the 4.x
branch any more.
I remember testing 5.x around the 5.3 release (2004) and 6.x shortly
after 6.0 (2005), and both em driver versions shipped with these
releases were having the same issues.
I haven't tested it this year yet, but even in case it's fixed, it's not
likely that all improvements will get back-ported to the older branches
(over 90% of my servers run something older than 6.x). But as long as
fxp works, this is a non-issue for me.
