Does anyone have ideas or plans for this? I know that (at least) "grep" and "index-pack" have their own implementations, and it would be great to just have one that all code can use.
For those who want to know, this question was motivated by a big delta tree occurring in [1]. index-pack does parallelize delta resolution, but it cannot split up trees into threads: each delta base root can go into its own thread, but when a delta base root is processed, all deltas on that root (direct or indirect) is processed in the same thread. I took a look to see if this could be parallelized, but thought that it might be better to standardize on a thread pool implementation first. Searching reveals [2], but I don't think it ever made it into Git.
