In bug 213927 <https://ews.webkit.org/status-bubble/403466/> I noticed some EWS were failing to apply the patch because the command timed out after 10 minutes without output. Example: https://ews-build.webkit.org/#/builders/10/builds/29642 This is because the patch does a bunch of copy operations, which end calling "git" "add" and this is slow and no output its produced for each one of this operations. This is not an issue with svn, since executing "svn add file" produces output. But git doesn't produce any output by default.
