Comment (by ttcoder):
Indeed kallisti5, and the work-around described over there works great,
thanks!
With this work-around in place, the priority I set seems heavy-handed now,
can be set back to 'normal' I guess
I might still work on getting some `strace` data to you pulkomandy; if
there is a part of haiku that still wants to access the deprecated 'hosts'
file there is probably interest in finding it and correcting it?
Indeed the strace indicates that ssh ''does'' access the hosts file,
though it does not readily indicate if that access comes from a userland
function (like gethostbyname() ..etc) in a library or the ssh tool or
something else:
