lsof said otherwise. Besides, if it read its seed from urandom, then it 
should not block on a lack of entropy, shouldn't it?

Both exim-4.50 from Sarge and exim-4.50-2bpo1 from Backports.org. 
libgcrypt is the one from Sarge (including all security updates of 
course).

I'll try to strace exim later this day and send the file to you and Marc.
