Dear friends of Falcon,
I just committed http://lists.mysql.com/commits/56749

It is unfortunately somewhat heavy patch, but it has to be so to run 
Philip's test without errors (and the next start after recovery  had 
been been checked for errors as well;))

Among the highlights in the patch  that contributed to successful 
recovery (I  use the word "highlights" secretly hoping to find the 
reviewer for the big chunk of code;)

- exclusively for Hakan, removing 10 seconds wait hack on CREATE 
TABLESPACE after DROP TABLE with the same file.

-Did you ever wonder how to posixly correct delete an open file on 
Windows? And do this without invalidating already open handles to it?
Or whether it is possible to write a function that tells whether 2 files 
are the same (or one is link to another),and the function will handle 
absolute/relative representation, case-sensitivity and other 
canonicalization issues on any OS? Both in this patch.

Thanks for your attention,
Vlad
