Currently the total amount of operational buffers cannot exceed 2^24 - 1
bytes (in other words must be less than 16 MiB).

There is more then one way to trigger this error.  The documentation just
states that the module is experimental. 

When you are using an experimental module that implements experimental
protocol draft then you have to be ready for any kind of errors, and not
only caused by the module itself, but in browsers too.

Though you are probably right, and this drawback should be documented
somehow explicitly.

That part of code lacks chain/buffer splitting mechanism as well as the
DATA frame adjusting feature.  It will be implemented, but we have no
ETA for this yet.
