My use-case is limiting the amount of memory dmd will allocate 
before -lowmem kicks in and collects (by use of 
--DRT-gcopt=heapSizeFactor on dmd), to accomodate for limited 
available memory. As pasted in the original post I seem to be 
able to do this manually.

So there is no way to set up a dub build configuration that 
automates this?
