Re: [reSIProcate] reSIP Process model

[Byron Campen <bcampen@xxxxxxxxxxxx>]

	Not strictly, no. Fifos are often used in cases where no  
multithreading is involved at all. Also, there are a few isolated  
places (in the stack) where communication between threads is done  
using something other than fifos (between the asynchronous DNS and  
TransactionState, for instance).

Best regards,
Byron Campen
