conccurrent read access to COMMITTED entry ?

["Jonghyuk Choi" <jongchoi@us.ibm.com>]

I am wondering whether or not it's possible to access
cache entries in CACHE_ENTRY_COMMITTED state concurrently.
For example, in line 690 of back-bdb/cache.c (or equivalent of
back-ldbm/cache.c),
can we change
if ( state != CACHE_ENTRY_READY ) {
to
if (state != CACHE_ENTRY_READY && state != CACHE_ENTRY_COMMITTED) {
?
Because the entry is already protected by read write lock,
it seems to me that concurrent reads to such entries may be permitted.
