or not a given name previously passed to temp_acquire is
currently locked.

+Returns true if the internal lock created by a previous C<temp_acquire()>
+call with C<NAME> is still in effect.
+
+When temp_acquire is called on a C<NAME>, it internally locks the temporary
+file mapped to C<NAME>.  That lock will not be released until C<temp_release()>
+is called with either the original C<NAME> or the L<File::Handle> that was
+returned from the original call to temp_acquire.
+
+Subsequent attempts to call C<temp_acquire()> with the same C<NAME> will fail
+unless there has been an intervening C<temp_release()> call for that C<NAME>
+(or its corresponding L<File::Handle> that was returned by the original
+C<temp_acquire()> call).
+
+If true is returned by C<temp_is_locked()> for a C<NAME>, an attempt to
+C<temp_acquire()> the same C<NAME> will cause an error unless
+C<temp_release> is first called on that C<NAME> (or its corresponding
+L<File::Handle> that was returned by the original C<temp_acquire()> call).

Subject: [PATCH 2/2] git-svn: allow git-svn fetching to work using serf

When attempting to git-svn fetch files from an svn https?: url using
the serf library (the only choice starting with svn 1.8) the following
errors can occur:

Temp file with moniker 'svn_delta' already in use at Git.pm line 1250
Temp file with moniker 'git_blob' already in use at Git.pm line 1250

David Rothenberger <daveroth@acm.org> has determined the cause to
be that ra_serf does not drive the delta editor in a depth-first
manner [...]. Instead, the calls come in this order:

1. open_root
2. open_directory
3. add_file
4. apply_textdelta
5. add_file
6. apply_textdelta

When using the ra_serf access method, git-svn can end up needing
to create several temp files before the first one is closed.

This change causes a new temp file moniker to be generated if the
one that would otherwise have been used is currently locked.
