Comment (by stephencronin):

 This problem still occurs in 3.1.1.

 It persists even after the Page is sent to Trash (the user gets a 404
 instead of the Post), until the Page is emptied from the Trash.

 The suggestion by solarissmoke is better than nothing. Ideally it would
 have to work both ways, ie if permalink is /%postname%/ then:

 1) check that no posts have this slug when generating top level page slug
 2) check that no top level pages have this slug when generating post slug

 It may not cover everything:

 a) it may not just be posts and pages we have to worry about (some people
 strip /category/ from URL for category pages for example);
 b) there is a very small chance that /%category%/%postname%/ posts could
 clash with a second level page.

 but they are real edge cases and as I said, it's better to do something
 than nothing.
