In theory, connects should happen "in background", but it looks as 
though this isn't always the case. I think what is going is that the 
"hanging" is actually waiting for a DNS server to provide an answer, 
rather than the connect itself waiting. The connect is started 
"non-blocking".

This may be better addressed in the "mojo" branch of the code, for those 
that are feeling adventurous. However, I can't guarantee it as the USP 
of this branch is that all of the networking infrastructure has been 
converted to use the "Mojolicious" perl web framework. If you want to go 
there you will need to "cpanm EV Mojolicious Mojo::IOLoop::ForkCall" (I 
think that's all) before running that branch. There are no other 
instructions. You can change branches back and forth between "master" 
(the one [nearly] everyone is on) and "mojo" and just restart the node 
in between swaps.

However, it doesn't address the crontab spawn issue (just because it 
hasn't bitten me yet). It ought to. I will probably change that over the 
Easter holidays.

For what it is worth GB7DJK has been running on this branch for some time.
