Hello.
After recent play with Boehm GC and Parrot's GC I have next "roadmap"
for properly encapsulate GC in Parrot. It will give us ability to
implement almost any kind of GC without reworking all things.
1. Extend GC_Subsystem struct with next functions:
a) allocate_pmc_header(flags)
b) allocate_string_header(flags?)
c) allocate_attributes(pmc_enum)
d) allocate_raw_buffer - to allocate buffer without pointers. Useful
for Strings, FixedIntegerArray, etc.
e) allocate_buffer - buffer which can contains pointers.
2. Change various Parrot_gc_foo functions to use it instead of
interp->mem_pools and remove interp->mem_pools.
3. Change current MS GC to allocate mem_pools in
GC_Subsystem->gc_private attribute.
Any thought/ideas/objections? If no one will complain I'll try to
implement it over weekend so we can ship it with 2.0.
