    Release 4.5: DB-__GT__set_isalive,,
    upgrade.4.5/deprecate, upgrade.4.5/elect)

m4_p([dnl
In previous releases, the function specified to the
m4_refT(dbenv_set_isalive) did not take a flags parameter.  In the m4_db
4.5 release, an additional flags argument has been added:
m4_ref(DB_MUTEX_PROCESS_ONLY).])

m4_p([dnl
Applications configuring an is-alive function should add a flags
argument to the function, and change the function to ignore any thread
ID and return the status of just the process, when the
m4_ref(DB_MUTEX_PROCESS_ONLY) flag is specified.])
