New String-related cmdline options

[David Dabbs]

Hi.

I see there are some new String-related cmdline opts. StringTableSize and
UseStringCache. Are there docs concerning the new switches and/or
diagnostics related to tuning? Just for grins, I specified AggressiveOpts,
but didn't see UseStringCache set to true, or did I misunderstand this
patch?

AggressiveOpts


Thank you,

David
