I would say since those thumbdrives are solid state, theoretically they should last forever, barring fire, flood, act of God, or static discharge . .
I'd like to do that myself, get an 8 GB thumb and install SuSE on it and run it on the St. Joe library machines, completely bypassing their native o/s. I don't think they'd like it unless I could prove to them it wouldn't muck up something in Windoze (version of the week).

In Linux disable the swap and use the no atime option in your fstab.
Turn off logging or log to a remote server.
