[PATCH] svn_dso_initialize can *silently* fail to create lock

Hi All,

The svn_dso_initialize can *silently* fail to create lock causing
failures later.

Attached patch fixes it.

Want to know what others would think about it.

With regards
Kamesh Jayachandran

Fix 'svn_dso_initialize' which was *silently* failing to create lock
and causing later accessors to fail.

* subversion/libsvn_subr/dso.c
  (svn_dso_initialize): When 'apr_thread_mutex_create' is not successful,
   abort.
