+fetching a URL:
+1. Check for URL in inflight URLs. If present, add cb, and return.
+2. Acquire lock at {cache}/{sha(url)}.lock
+ retries = {cache-lock-retries, def=10}
+ stale = {cache-lock-stale, def=60000}
+ wait = {cache-lock-wait, def=10000}
+3. if lock can't be acquired, then fail
+4. fetch url, clear lock, call cbs
+
+cache folders:
+1. urls: http!/server.com/path/to/thing
+2. c:\path\to\thing: file!/c!/path/to/thing
+3. /path/to/thing: file!/path/to/thing
+4. git@ private: git_github.com!npm/npm
+5. git://public: git!/github.com/npm/npm
+6. git+blah:// git-blah!/server.com/foo/bar
+
+adding a folder:
+1. tar into tmp/random/package.tgz
+2. untar into tmp/random/contents/package, stripping one dir piece
+3. tar tmp/random/contents/package to cache/n/v/package.tgz
+4. untar cache/n/v/package.tgz into cache/n/v/package
+5. rm tmp/random
+
+Adding a url:
+1. fetch to tmp/random/package.tgz
+2. goto folder(2)
+
+adding a name@version:
+1. registry.get(name/version)
+2. if response isn't 304, add url(dist.tarball)
+
+adding a name@range:
+1. registry.get(name)
+2. Find a version that satisfies
+3. add name@version
+
+adding a local tarball:
+1. untar to tmp/random/{blah}
+2. goto folder(2)
+
+adding a namespaced package:
+1. lookup registry for @namespace
+2. namespace_registry.get('name')
+3. add url(namespace/latest.tarball)
