10.0.3 Leaking Memory

I have been noticing extreme memory leaks in Safari, to where it uses over 68GB of app memory after only an hour or two usage. Since then I have taken the following steps:

• Uninstall all extensions and plugins.
• Deleted /Users/<username>/Library/Safari folder while Safari was quit, then started it up again.

The extreme memory leak has been averted, but now it still leaks memory when only sitting at the favorites page right after opening. First it starts out at around 30MB memory usage, but works its way up by about 1MB per minute going forward.

I also ran the following command to determine if there are any leaks:

leaks `ps ux | fgrep -i SAFARI.APP | fgrep -v fgrep | awk '{print $2}'`

This resulted in the following output:
