Indeed, watching strace for longer shows that (I was always impatient
before):

    recvfrom(5, "\366\310\201\202\0\1\0\0\0\0\0\0\5rotor\0\0\1\0\1", 2048, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.1.96")}, [28->16]) = 23
    poll([{fd=5, events=POLLIN}], 1, 4996)  = 0 (Timeout)

I remember now that we have been having DNS hiccups here and that would
seem to be another symptom of that problem. Thanks for the workaround.
I'll ping our sysadmins again :) .
