4433dbb5f5 userdata with finalizers are kept in a separated list ('udgc'), instead 
of at the end of 'rootgc' (which was renamed to 'allgc', as it is not
"root" in the usual meaning for collectors)

5cb128ea54 BUG: emergency collector might resize 'strt' (string table) when 
creating a new string
+ atomic and markroot steps has some cost
+ full collection must leave collector in proper state when mode
is generational

write barrier, so GC should visit them in the atomic phase.

e091a254df new way to GC stacks: the entire stack must be correct all the times;

that 'top' may go up without cleaning the stack.
