Oh I think I might have misunderstood your question. For git.git it will 
still die() but for other users that arrange for xdl_realloc() to return 
NULL on failure it will return -1. The same applies to the comments in 
the previous two patches about XDL_[CM]ALLOC_ARRAY() returning NULL on 
allocation failure.
