Good to know.

BTW, you still did not tell us where those reallocs come from (not all
the allocations, only the reallocs). From a quick search, Lua reallocs
in three places:

- the parser (reallocs all kinds of arrays used to represent a function);

- the stack (deep call chains, or new coroutines);

- tables (usually new arrays growing);

Can you find out which of these is calling so many reallocs?
