 Hi,
 
 I just wanted to inform you that this problem report can be closed as I was
 wrong with the cause of the clock_gettime()-calls. They were, in fact, issued
 by varnish.
 
 They were issued so often because the return code of usleep() wasnâ??t checked
 and NetBSD does not handle values >= 1,000,000. See ticket #475 [1] in varnish
 bugtracker.
 
 So, sorry to have wasted your time and thanks for your help.
 
 Best regards,
 Michael
