Process stops at line 17384 in clamav-strace:
futex(0x25944f0, FUTEX_WAIT
Line terminaison was written ("2, NULL) = ? ERESTARTSYS (To be
restarted)") when I have pressed ctrl+C, but process remains in sleep
state. I have tried kill -15 (without any success). Only kill -9 kills
clamd.
Can you give this patch a try?

David,
I have tried your patch with icemonkey and it hangs (in a futex).
