reallocating data not covered by gc

reallocating data not covered by gc

[Klaus Schilling]

Is it dangerous to reallocate from scheme wrapper code
 pointers that have been allocated or 
declared NULL in code that was executed before boot_guile was called?
does declaring critical sections arround those reallocation calls
smoothen the situation?

Guile doesn't care about what you do with libc's malloc/realloc/etc. so
you can essentially use them to do whatever pleases you.  :-)

Critical sections are unrelated: they are supposedly a way to block
execution of asyncs (although it's not all that clear from looking at
the code, especially since `scm_i_critical_section_mutex' doesn't seem
to be really used...).

Thanks,
