One thing we noticed when going from IDM 3.6.1 to 4.0.1 at a customer
was that the 4.0 remote loader had huge JVM defaults compared to the
older version.

IDM 3.6.1 (32 and 64 bit) had min = 8MB, max = 64MB
IDM 4.0.1 (64 bit only) has min = 128MB, max = 512MB

Anyone know why these were bumped so much?
