Lua memory management with long-running processes?

[William Trenker <wtrenker@...>]

I've been experimenting with Lua (5.0.2) running Xavante in a Linksys
WRT54G wireless router.  The software runs just fine and Xavante,
coupled with Cgilua, makes a great little application server.  I am
wondering if anyone has any experience with long-running lua
processes?  For example, are their any concerns regarding garbage
collector settings and the possible impact on memory management such
as heap fragmentation?  The very fact that Xavante / Cgilua / Copas
exist encourages me that the Lua developers see Lua as a serious
long-running contender.  Lua is fabulous!

Thanks very much,
