Hey Henry,
it is easy to test and find the current realfree memory allocator
implementation limit by Oracle if you have enough memory ;-)
Regarding the general realfree memory allocator ( mmap() and munmap() ) and
its advantages you can check this Oracle-L post including the links:

Stefan,
That doc looks interesting. Wish I knew more about _use_realfree_heap. Doing
some searching (my current setting is TRUE). Also wonder if the 16GB
hard limit mentioned in that doc could also be 32 GB as I am seeing.
Henry
