Does TSVN cache/reuse svn_client_ctx_t handles? In 1.7 the client
context contains an opaque wc context which in turn includes a
database context, svn_wc__db_t. The database context caches sqlite
connections and has a cache mapping directory->database.
Quite when TSVN should create/destroy svn_client_ctx_t is an
interesting question. Reusing a long-lived context (or perhaps a
small number, one per-thread say) is likely to make individual svn
calls faster. However the open database handles means that Windows
won't be able to delete root directories. It's not clear to me how
or when TSVN would close those handles.
