Summary	0005105: disk system was not able to keep up with Ardour
Description	I can't export in wav with Ardour 3.0beta5 a one track session (2min) without efect. I tried to change the playback buffer, and I obtain only a few seconds in the wav. For example, if I choose 60 seconds for the playback buffer, I obtain a more o less 60 seconds of music in the wav file. Once the buffer is empty, it seems not to fill it. I have the message : "The disk system on your computer was not able to keep up with Ardour. Specifically, it failed to read data from disk quickly enough to keep up with playback." I can listen the music before export it without any problem. With Ardour 2.8.12, in the same configuration, no problems to export Jack version : 1.9.8 Tango Studio (Ubuntu 10.04 based), linux kernel : 2.6.32-41-lowlatency Gnome : 2.30.2 Audio interface : Audiobox USB 1G of RAM My swap (2G) is on another hd than where I try to write the .wav hdparm : Timing Cache Reads Timing 250 MB/sec Timing buffered disk reads 44MB/sec. Should I change something in Ardour3 to have the same result than in Ardour 2.8.12 ?
Steps To Reproduce	- open jackd - open ardour - create new sesion - import wav file as a new track - export in CD quality (Wav, 16bit, 44.1 kHz) - after the play buffer is empty (it depends on what i choose on the Preferences), error message : "The disk system on your computer was not able to keep up with Ardour. Specifically, it failed to read data from disk quickly enough to keep up with playback."
Additional Information	I don't really know how to use gdb, so I copy what I have see on the terminal using ardour3 --debug in the uploaded file.
