TODO items for public-inbox
-(Not in any particular order)
+(Not in any particular order, and
+performance, ease-of-setup, installation, maintainability, etc
+all need to be considered for everything we introduce)
+
+* general performance improvements, but without relying on
+ XS or compiled code any more than we currently do.
* mailmap support (same as git) for remapping expired email addresses
* Consider storing git blob ID in Xapian doc data to avoid ref
and tree lookups based on Message-Id.
+* streaming Email::MIME replacement: currently we generate many
+ allocations/strings for headers we never look at and slurp
+ entire message bodies into memory.
+ (this is pie-in-the-sky territory...)
+
* Allow in-place Xapian updates without clobbering the whole
index (versioning each doc data entry?) for big archives
