How about copying the entries that you do want into a new table, then make the old table equal to the new one (leaving all that other stuff to the gc). Would that work? 

new_t={a="new", b="old}
t=new_t

Subject: Clean the table

I have a table:
t={ 1,2,3,4,...9999,10000; a="new", b="old"}

Which is the best and faster way to clean
the lfieldlist "[1]...[10000]" from the table?

I do:

for i=1,getn(t) do tremove(t,i) end

but it's very slow.

Another way:
for i=1,getn(t) do t[i]=nil end
t.n=0
This is faster.

An idea...
