> Can new and Guile's own allocation scheme coexist?

Yes, certainly.  However, Guile's allocation scheme is quite different
from new/delete or malloc/free.  You don't have to explicitely delete
or free a object, but you have to take care that the object is always
properly visible to Guile's garbage collector.  Objects on the C stack
and inside other Guile objects are automatically visible, but other
objects might not be.  For those, you have to call
scm_gc_protect_object and scm_gc_unprotect object at appropriate
times.  Or turn your structure into a smob.
