[ruby-core:28636] [Bug #2723] $: length affects re-require time of already loaded files

Issue #2723 has been updated by Greg Hazel.


The speed in SVN trunk is much better:

$:.length: 9,    0.000090 seconds
$:.length: 12,   0.000150 seconds
$:.length: 21,   0.000250 seconds
$:.length: 48,   0.000490 seconds
$:.length: 129,  0.001160 seconds
$:.length: 372,  0.003140 seconds
$:.length: 1101, 0.008981 seconds

Still not constant, which I think it probably could be if the absolute paths of both "/path/to/foo" and "/path/to/foo.rb" were written to $" when "foo" is loaded. Much better, though.

Any chance this speed improvement will be backported to 1.8.x?
