Yes, you can stop (disconnect) the slave, and then restart it. I
never really understood the Stop buttons on the buildbot web pages,

Sorry, I couldn't help noticing this:

0x is not 32 bit, it's 16 bit.. Should that be 0x instead?
No, this 32bit comment

Try running pypy with the -s option. Likely, it doesn't remove them
