Re: Cloning "preforked" Lua state

[Asko Kauppi <askok@...>]

This would be a welcome feature, if possible and fast.

It could be used i.e. with servers, where currently Lua states need  
either to be recreated from scratch for each query, or carefully  
restored to known "clean" state after finishing a query. This sounds  
like a simpler way to me.

Maybe code from Lanes can be used to copy the entries of the template  
state. I should do some speed tests on that (or do the code and let  
_you_ run the speed tests).  ;)
