Description Jesse Glick 2004-09-08 19:20:50 UTC 
Acc. to OptimizeIt, when closing a lot of projects
(20 or so), almost 9% of CPU is spent in
FileObject.getURL, almost all of which is from

CP.aP -> OPL.close -> OPL.saveProjectList ->
OPL.projects2URLs -> FO.gURL

Now this is quadratic time! Each project is closed
individually, and each time, the whole project
list is saved again, meaning each (remaining)
project has to have its URL checked.

Would be faster to just have a method
OPL.close(Project[]).

This issue was solved long time ago. Because nobody has reopened it neither
added comments, we are verifying/closing it now. 
If you are still able to reproduce the problem, please reopen. Thanks in advance.
