One problem with this model currently is inlining: once the  
implementation of a unit containing an inline procedure is compiled,  
its interface crc changes (because the code of the inlined routine is  
part of the interface), and this can trigger recompilations of other  

An easy solution is to not let the code of inline routine (and the  
flag that indicates that it's available) influence the interface crc,  
but in that case it won't be inlinable in units it depends on in its  
implementation. Doing that would probably solve a lot of crashes and  
other errors that currently exist with the unit loading though.
