It shouldn't matter, but the accounting software on the network I'm using freenet on (planetlab) is dumb and shuts my nodes down because it works out my mem usage based on the ps table. > How threading is handled is an interplay between the JVM and the host system, > you can also influence it (mostly for backwards compatability when the default > behaviour breaks) with the LD_ASSUME_KERNEL environment variable which you've > probably noticed start-freenet.sh does for known problematic cases.
