I must admit that I've never seen this on a Unix platform. But
unfortunately it is common use on M$-Windows platforms to replace a
written "free()" to different kinds of heap allocation free()'s depending
on the "memory model". Is this reason enough to have such functions?
Yet another pointer might be c++. If you use Guile inside c++ code you
could define a class::free()... This a reason?
