Table CACHE/NOCACHE

Guys,

Help me figure this one out. Was helping a colleague diagnose slow response time (8.1.7/Solaris running Peoplesoft ). x$bh showed 102,248 out of 170,000 buffers belonged to a single table, which he said he cached explicitly. He did "NOCACHE" (on my suggestion) on the large table.
I still find that the table is in buffer cache (even Buff# haven't changed - starts with buf#=1 - not sure if this means LRU end) even after a week. DB cannot be bounced since it is production.
Do you know of any reason why it is not flushed out of cache when table is altered to NoCache?

Thanks,
Ravi.
