Seems to help:
merkaba:/tmp> grep -c "stat(\"/etc/localtime" strace-blub.txt
0
merkaba:/tmp#1> grep -c "stat(" strace-blub.txt
998
Still KMail was blocked for some time, but appeared to be shorter, definately
wasn ´t a minute, but this was also during KDE session startup with Akonadi
starting and MySQL was using 120% CPU (possibly due to other initialization

I wait for some bigger mail batch to arrive and retest then and add comment to
bug.
