"Filename -- Root": the "--" here will not work as we want obviously. For
example, Filename = "e:/aa.couch", Root = "E:/", then (Filename -- Root) =
"eaa.couch". Not to say "/" and "\" on Windows.

Windows' deny-of-access here seems to be resonable. Maybe CouchDB need a
more gracefull process on this. Currently, there is a 5sec delay before
closing the old .couch file handle, and if CouchDB is suffering heavy I/O
load, compaction may fail.

For 0.7.2, after some fix, all cases except 1 can pass on Opera, while IE
just cannot show couch_tests.html at all. For 0.8.0-incubating, IE can show
test cases, but both Opera and IE can run none of the cases successfully,
while Firefox can run most of the cases successfully (except 2, one for
Unicode, and one for compaction).

The problem for Opera is that when creating a DB, there should be a "PUT"
request, but a "DELETE" is instead. This should be the fault of Opera's JS
engine? I am not sure, but the phenomenon is strange.
