When an error occours (or the peer disconnect), we return from decorator
as an error is published to the chan.
There are though still 5 or 6 goroutines that want to write on that
channel and at least 3/4 of them will be hanging, leaving them stuck
publishing on the chan.
This though is probably not the cause of
https://github.com/status-im/infra-eth-cluster/issues/39
fills up the stack trace with hung go routines.
