1.4.1 SPDY error FIXME: chain too big in spdy filter

[ctrlbrk]

What is the maximum amount of the buffer?  I could not locate any
documentation on any of this with regards to how it would cause an error on
SPDY.

And doesn't "FIXME" indicate this is a bug?  Why would it be in the code
otherwise?

I already removed SPDY and the errors went away, as did the problems users
were experiencing downloading larger files.  But I would like to add it
back.
