Comment(by jorgearevalo):

 Of course. I'm copying the things that work on PostGIS. But the changes
 can be summarized in:
   - using global vars to store memory allocators, instead of a struct
 (rt_context), that must be allocated in every function call.[[BR]]
   - working on the SQL calling function memory context.
 "MemoryContextSwitchTo" is used only when you need a persistent memory
 context to store info (SRF).[[BR]]

 So, it's not so huge change, really.
