The answer appears to have to do with SIGALARM.  I had a handler for
SIGALARM for a portion of the code written before it was ported to gtk. 
It seems that input_add returns when a SIGALARM runs.  I solved the
issue by doing the Right Thing: using Gtk->timeout_add and Gtk->timeout
remove.  The code is cleaner and it has run reliably for 18 hours (in
contrast to about one second) so I suspect that the problem is fixed.

I don't understand how timeout_add could be a clean substitute
for input_add. What you probably want to check is the last arg to
your handler:

Gtk::Gdk->input_add($fileno, ['read'], sub {
        my $condition = pop @_;
        if ($condition->{read}) {
                # it's safe to read
