Is there any possible memory leak in GC?

[Herbert Euler]

Hello,

Here is just a possibly stupid question on GC.

After watching the use of `cons_free_list', I am confused about it.
`cons_free_list' holds the unmarked cons cells during GC sweeping.
When `cons' creates new cons cells, it picks any ones in
`cons_free_list' if possible.  But each time when sweeping happens,
`cons_free_list' is reset to 0, and its previous value is lost.  Since
GC can run at any time with `garbage-collect', will this lead to
memory leak or not?

Regards,
Guanpeng Xu
