turn up a link.  For many years Chez scheme had a "saved heaps"
capability.  It was recently dropped because of the
preponderance of SE Linux which randomizes addresses and messes
it up, but here's the doc for V7:   I've always wondered why
there weren't more language implementations with saved heaps.
Under Chez the startup times were amazing (a 50KLOC compiler a
two second load would become 4 milleseconds).  Google Dart

with slow load times like GMail.  Chez also has pretty fast
serialization to a binary "FASL" (fast loading) format, but I'm
not sure if those were mmap'ed into the heap on load or required
some parsing.  The gamasutra link that Mikhail provided seems to
describe a process where the
