Mostly we store strings in the cache so it is not a real problem

But if i do not need eviction policy, if i want to keep them forever?

True, and i am still using it this way, i even use  global arrays to be 
able to get all values easily. But i have a lot of filters and callback 
procedures that are called from different places even from C modules. 
Calling Tcl wrapper all the time is a big slow down especially if i need 
to process several hundreds of rows, tls will be a big improvement in 
this case.

But i agree that functionality-wise it is the same
