Hitting proc_open limit

[weierophinney]

I'm attempting to run satis to re-create the Zend Framework composer repository, and using the new "archive" feature to grab download zips from GitHub.

I have around 80 repositories I'm scanning.

I think somewhere around 75, I got an error message:

Fatal error: Uncaught exception 'ErrorException' with message 'proc_open(): unable to o create pipe Too many open files

Fortunately, re-running the command, satis was able to discover the files it had already downloaded, and finished quickly.

That said, this would be a nice issue to resolve, for those building composer repositories from many VCS sources.

I know it might take you a while, but would you mind rerunning it with an empty cache and --verbose so as to get a full stack trace? Just wondering exactly where this came from. Alternatively if you want to share your satis config that might work too.
