As Roger wrote to list before few months, experimental version of Tor optimizes RAM usage and I can confirm that. Before I switched to 0.2.1.x branch, my node used +- 2x more RAM (not sure exactly).
ad "top": Dont forget to buffers and caches. So final amount of actually used RAM by system is: Used - Buffers - Cached. My experience is that blank Debian system take around 10MB RAM. Currently, my home server running Xen dom0, xen-tools, sshd and nagios nrpe takes 47 MB RAM. Tor process for node like yours takes around 50 MB RAM. So I think 64 RAM is enough to run Tor without problems.
