squids ICAP implementation does not check mem-store size before reading from 
an
ICAP-server.
If the user does not confirm browsers download-message-box, squid keeps on
reading data from the ICAP server into the memory store, whilst no more data
can be delivered to the client. 
Thus the memory store is growing and squid may - in worst case - consume 
memory
up to the size of the users download.
