scm_weak_symhash

Hi,

I don't understand the purpose of the weak_symhash table. 


When something like `(define hugo 12)' is entered, the symbol `hugo'
is interned in the weak symhash table. Since nothing prevents `hugo'
from being garbage collected, this symbol may or may not exist, when
the evaluator is called, no?

Well, let's assume the symbol is still there. The evaluator then calls
`sym2vcell', which copies `hugo' from the weak symhash to the symhash
table. But what if the symbol has been garbage collected so that
`sym2vcell' fails and the evaluator can't give it is value?
