I haven't tried it yet. Currently, we are using RVM to install ruby, but
as soon as I've some time, I'll setup a source version of ruby and apply

Yeah - I've also ask a college to test it under FreeBSD (without Jail) and
he can't reproduce it either. It seems to be a Jail problem (I would run

Yes - I'm pretty sure that SMP is involved.
