Calling runtime.Stack requires the buffer to be big enough to fit the
goroutines dump. If it's not big enough the dump will be truncated and
the value returned will be the same size as the buffer.
The code was changed to handle this situation and try again with a
bigger buffer. Each time the dump doesn't fit in the buffer its size is
doubled.

pkg/ is a collection of utility packages used by the Docker project without being specific to its internals.
Utility packages are kept separate from the docker core codebase to keep it as small and concise as possible.
If some utilities grow larger and their APIs stabilize, they may be moved to their own repository under the
Docker organization, to facilitate re-use by other projects. However that is not the priority.
The directory pkg is named after the same directory in the camlistore project. Since Brad is a core
Go maintainer, we thought it made sense to copy his methods for organizing Go code :) Thanks Brad!
Because utility packages are small and neatly separated from the rest of the codebase, they are a good
place to start for aspiring maintainers and contributors. Get in touch if you want to help maintain them!
