[darcs-devel] [patch2027] fix creation of temporary directories

[Ben Franksen]

Ben Franksen <ben.franksen at online.de> added the comment:

As processes that run darcs commands are supposed to be short-lived, 
perhaps we should make withDelayedDir the standard way to handle 
temporary directories. The problem here is that we usually read hashed 
files lazily, which makes it pretty hard to reason about when it is 
safe to finally remove the directory and its content.
