asterisk users - Nov 2005 - Read() application behavior change: bug or feature?

Bug or feature?

I'm fairly sure this behavior changed between CVS HEAD Nov 1 and RC2.

In the earlier release, I could successfully execute the Read() 
application immediately following answering a (SIP) channel.  In the 
current RC2, Read times out without detecting user input, unless I 
precede it in the dial plan with Background, as below.

exten => s,1,Answer
exten => s,n,Background(silence/1)
exten => s,n(readopt),Read(ACCEPT,,1,,,10)
