pub(super) const MAX_INFLIGHT_FETCHES: usize = 16;Expand description
Max in-flight git diff -- <path> subprocesses during a scan.
macOS’s default soft open-file limit is ~256 and every git child
holds stdin/stdout/stderr pipes plus a handful of git internals
(~6-10 FDs); firing all N at once on a 100+ file refactor
branch trips EMFILE. 16 keeps total well under the FD ceiling
while still giving a 16× speedup over a sequential loop.
