Windows 'Access Denied' Update

From: D.J. Heap <dj_at_shadyvale.net>

Just a quick FYI for any who care...

On a fresh XP machine with Index Server off and no AV stuff installed,
I've been multi-stress.pl-ing and get the 'Access denied' problem on
FAT32 as well as NTFS. *And* if I patch svn_io_file_rename to attempt
100 retries, it seems to fix the rename, but then I occasionally see
svn_io_file_remove failures with 'Access Denied.'

It does take multiple stress.pl's and usually several hundred revisions
at least.

I also converted my test-repro program to use APR thinking maybe it's
use of overlapped i/o might have something to do with it...but alas, no
luck. So I'm still missing something that Subversion is doing to
trigger the problem, I guess.

Anyway, it's not just NTFS and it's not just renames. Yay, fun.

BTW, these are the only failures I'm seeing anymore with BDB 4.0 --
thanks to all the recent fixes I haven't had a single case of the
deadlock problem, or the 'unable to open environment' problem. (BDB 4.1
has been behaving much better than it was, also, but performance is
still poorer and it often hangs -- all processes get hung up, even
db_archive and I have to kill them all off and recover the db. I'll get
a stack trace tonight or tomorrow and post it.)
