Caching of describeTable

Hi,

Maybe I just need to RTFM but this one is a quickie: Is there a caching
solution for Zend_Db_Adapter_xxx::describeTable() ?

That one gets called quite frequently, and is very unlikely to change in
production environemtns. Caching it somehow would be a smart idea.

If nobody has suggestions, I'll do some hacking later and post an
article about it.

TIA,

Shahar.
