I've been in this situation.

Where I'm being told, "Hire more developers! We need more developers!" I respond with, "I don't need any more on my team right now. We can't handle more with our processes and the head count on our other teams."

That's not important though. To the people I was working with, more developers meant you could do more work, even if we didn't have a plan for what that work would be yet. Incredibly frustrating since more devs could actually contribute to gumming up the works if not brought in appropriately.
