Is there a limit to how many 301 (Permanent) redirects I can do on a site?

Is there a limit to how many 301 (Permanent) redirects I can do on a site? How about how many redirects I can chain together?

Other things to watch out for with chained redirects:
- Avoid infinite loops.
- Browsers may also have redirect limits, and these limits can vary by browser, so multiple redirects may affect regular users in addition to Googlebot.
- Minimizing redirects can improve page speed: http://code.google.com/speed/p....age-speed/docs/rtt.h
