Can you try this alternative approach? Every time you create in Lua a
userdata with external memory, call lua_gc(L, LUA_GCSTEP, n), where 'n'
is the amount (in Kbytes) of external memory. That way, you also speed
up the collector, but more in tandem with memory consumption.  (This
call will closely match what Lua would do if the userdata itself was
that big.)
