I don't think the thread manager is an appropriate model for this, as  
it may have to be changed depending on internal requirements of the  
RTL (for example, a big shortcoming currently is that the thread  
manager generally lacks error reporting functionality, other than  
triggering run time errors). An abstraction layer on top of the thread  
manager seems more appropriate for the purpose of offering a portable  
procedural threading interface.

It's similar to how you don't directly use the memory manager, but  
instead have to use getmem/freemem/...
