Roberto Ierusalimschy a314409dba in generational mode, an emergency collection can turn any object black 
during any memory allocation +
'luaT_getvarargs' may reallocate the stack, and therefore the top must
be correct.

Roberto Ierusalimschy af70905246 no need to check whether libraries and host use the same kernel;
