You could have a 10-second "heartbeat" that does:
my $first_free = do { open my $x, ">&STDERR"; fileno $x };
That will tell you the fd number of the first free file descriptor.
You can then adjust your timeout value to be inversely proportionate
to that number.
Yes, it's not the same as the number currently in use, but it's a
cheap number to get.
