>From perldoc perlsyn:
If any part of LIST is an array, foreach will get very confused if
you add or remove elements within the loop body, for example with
splice. So don't do that.
A solution that doesn't violate the "don't do that" rule would be to
use a while loop instead of a for loop.
You can get away with the following, so long as @$servref has no
undefined elements.
while ( my $server = shift @$servref ) {
.
.
.
}
