I added two repositories (one medium sized - 2493 commits, and a large one - 30750 commits
, 4100 branches), to phabricator, which runs on a Ubuntu virtual machine.
Everything works fine with the medium sized one, but the large repository gives an Update error in the diffusion interface after everything was imported successfully. Manually triggering the update gives a more detailed error message:
```
$ ./repository update R8

I wouldn't be surprised if the error is caused by the fact that the commandline is too long, since the limit on my system indeed seems to be less than 191,000 bytes.
Anyhow, since the theoretical POSIX smallest allowable upper limit is `4096`, shouldn't phabricator use xargs or something for commands like this?
