Although handle count may grow slowly over time (I found an XP client with a handle count of 1,910 but it has been running for 10 months; found another XP x64 client running for a day or two with a handle count of 49) with v4.0.3.1 it does not seem to be increasing at the rate of 1 handle per minute. Agent v4.0.6.1 likewise does not increase handle count at the rate of 1 per minute.
I don't have any other versions, installed or otherwise with which to test.
