synchronized ChannelBuffer + ChannelBuffer pool

[rzo]

Hello,

first: thanks for this great framework.
During my tests with netty I have run into issues because I was assuming 
that buffers in netty are synchronized.

I think it would make sense to provide a 
Channels.synchronizedChannel(...) similar to java's 
Collections.synchronized...()

What do you think ?

I have overcome the synchronization issue by creating a new 
ChannelBuffer before sending it downstream.
How expensive is ChannelBuffer creation/garbage collection ?
Would a buffer pool make sense ?

is ChannelBuffer.discardBytes() better than creating a new buffer for 
sending downstream ?
