Still running on the netbook after 12 hours -- I'm writing this post on the TinyCore netbook, with Pharo Launcher & Pharo in the background. Here's some of the system stats:

Next test will probably be an old Intel-powered Chromebook. (They can boot thumbdrives.) Then my RPi3. (It's a 3B model -- 64-bit ARMv8, but they're supposed to be backward-compatible with 32-bit ARMv7; there are TinyCore builds for ARMv6, ARMv7, and ARMv7l, so I'm not sure what will work there.)
