Not exactly, the main problem is that the Lua VM is not living
forever. it's started on demand and dies as soon as request
processed. I can create the pool of the VMs, it's not a
problem but it leads to another problem - how can I share
`package' table between all VMs? How can I share the code
compiled and being executed in one VM with another one? How can
I invalidate compiled code when disk file has been changed? How
can I throw away the expired code from the cache? I'm afraid
only by full replacement of the `require' function as it is
now. maybe I'm wrong.
