No, it's not. We should add an RA method that indicates that the process
is being initialized and advise SVN to perform recovery. libsvn_fs_base
can then decide through other means what to do with it (i.e. via a new
named shared memory segment that does refcounting). For example, if
another process has the repository open, then it can skip the check.
However, for mod_dav_svn, the time to invoke the check would be at the
post_config hook. This also allows immediate feedback whether the
repository is in a 'good' state before the rest of httpd is initialized.
If it fails the check, then httpd will never come up: which, IMHO, is a
good thing. -- justin
