paramiko.util.load_host_keys with big file known_hosts

[Christophe GUILLOUX]

(paramiko 1.7.5)
The function paramiko.util.load_host_keys is very low when known_hosts is big. I have 541 entries and it takes 1 minute.
(And i don't know how if it works with hashed host.) CPU load is 99%

One entry for example :
|1|ECaT+rJav/aUZOcW6ZJwXJonlGU=|2Z5AAk2zXhB5V3Ttv4bYcwxAn0g= ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAqw6g31pWeeArFvfLxy93Sl0uzVslnpXIwEI9GInpSlZFMcPd5xJq91mbP+9T9BJohusVrPnn4BKy4OMKzG1tON8+2aqJRIDth3Ac9zeRPVKrWzPanSvKZoMn3zBWTI9oCcsCmELKrYO1A2NosiI4mXuTW6HIBZs+f0ff6P3cvTT+PereGH6AoKORkV5nveJs84qiUj6ybU8E0ZXbF+Hua1toHIGE7wGyNSXGHII1BLI+b/aCZ/45wGmgvSc2K2WiRCuCEy8Z5zJD/oKOgyHP1JCOViE7Pac3IMhNhSTxRTnaWWiKQjpF+n/Y651Z+JC8PU6fc/mnQiV5UGvmzEiaXQ==

>>> print(time.time()); x = paramiko.HostKeys("/Users/robey/.ssh/known_hosts"); print(time.time())
1257132086.18
1257132086.32

$ wc -l ~/.ssh/known_hosts
     513 /Users/robey/.ssh/known_hosts

maybe something else is going on? python seems to load that file relatively quickly.

Sorry, i forgot this bug.
No problem with my ubuntu 10.04, i think we can close the bug.
