Pulse doesn't tell you about xruns. It makes whatever it has as an input 
fit what the output needs by whatever method needed with the least amount 
of audible distortion. Just like most people can not tell the difference 
between an MP3 and the wav it came from, most people can not tell the 
difference from pulse's input to it's output. But in the same way you 
wouldn't use MP3 as a DAW tracking standard, I wouldn't use pulse for 
recording unless there was no other way. (skype phone call for example)

It is another way of saying it handles just 
about anything gracefully.... even skype. But it is a desktop audio system 
that is designed for audio consumption, not audio creation. It does really 
well at what it is designed for and even not too bad at what it is not 
designed for.

I run pulse on my desktop as a front end for jack. Pulse sees jack as the 
(only) audio device. I try not to record anything so badly I need to use 
the noise remover in Audacity.... the Audacity noise removal plugin being 
the only feature I can't find elsewhere.

letting Pulse directly see/connect to any real audio device will 
compromise the pulse-jack bridge and cause xruns.

I hope I have made clear I am not against pulse. It works very well in the 
place it was designed for. I still prefer a boxend wrench over an 
adjustable wrench when I work on a truck too.... but will use vicegrips in 
an emergency. Every tool has it's place.
