If "init.ora" resource_limit = true, and idle_time set in profile.

When idle_time exceeds, the session status becomes 'sniped' in v$session,
but sniped sessions never get cleaned up.

Using 'alter system kill session' to kill the session, session status becomes
'killed' in v$session, but still is never cleaned up.


我对下面这两句狂怀疑：
but sniped sessions never get cleaned up.
but still is never cleaned up.
难道如果设置了resource_limit = true, and idle_time　in profile，又没有通过kill -9 os层面来杀,session量就会只增不减，直到超过最大并发数？pman真的不管sniped 和killed 的sessions？
