Stupid question.. process sizes (x86_64)

[Timo Kujala]

Hi,

Just stupid question, but those VIRT/SHR values in top (and also in ps-listing)
look horribly large. Is my system just messed up or is this something 
normal with brave new 64-bit technology :)

System: x86_64, kernel 2.6.3-253 and development-version of Fedora core.
