3229	Mention Deferred chaining limit in howto/defer.html	Scramblejams	ivank	"Chaining more than ~250 deferreds results in a recursion error. See attached code for demonstration of the problem, and the following email for a description of why it occurs:

(Note: You may have to play with NO_OF_DEFERREDS in the sample code. On my system, Python 2.5/Twisted 8.0.1, I needed to use 332. You may need more or fewer.)

In the meantime, or if this gets classified as wontfix, this issue should be covered in the deferred documentation, preferably here:
