epriestley f7464400a5 Limit memory usage of ssh-exec during large pull operations
Summary: Fixes T4241. Ref T4206. See T4241 for a description here. Generally, when we connect a fat pipe (`git-upload-pack`) to a narrow one (`git` over SSH) we currently read limitless data into memory. Instead, throttle reads until writes catch up. This is now possible because of the previous changes in this sequence.

Test Plan:
  - Ran `git clone` and `git push` on the entire Wine repository.
  - Observed CPU and memory usage.
  - Memory usage was constant and low, CPU usage was high only during I/O (which is expected, since we have to actually do work, although thre might be room to further reduce this).
