Is it possible to get a stack trace of the script while it's blocked?
From /proc/$pid/stack ?
The test takes 30sec on a debug-heavy build for me so capturing a stack
a couple of minutes after starting should should us where it's stuck?

The only thing I can see that may be blocking is getaddrinfo()... maybe?
Is there anything special going on with address resolution?
