OK while reading about this file I remembered a similar issue I had with 
Opera in the past, where the fix was to disable IPv6. IPv6 was already 
disabled on my system globally, but this apparently doesn't prevent 
individual programs from trying to use it, and I just found that my 
local DNS server had it enabled. Disabling it there made "erl" not hang 
at startup anymore.

Thanks for the help!
