Summary: Use with vlc blocks Pd

Initial Comment:
pd-extended 0.43.1-extended-20120317
Tcl Version: 8.5.10
Operating system : Ubuntu Oneiric
CPU type (tested with 2 computers) : i386 (package : Ubuntu Oneiric i386) and amd64 (Debian/squeeze amd64 also calles debian stable)

jack :
Version: 0.3.8
Compilation: Jul 9 2011 09:51:20

Jack Messages window : ERROR: JackAudioDriver::ProcessGraphAsync: Process error

In Pd-extended on audio ON used with or without vlc :
	JACKerror: Cannot lock down memory area (Cannot allocate memory)
	JACKerror: Cannot use real-time scheduling (RR/5)(1: Operation not permitted)
	JACKerror: JackClient::AcquireSelfRealTime error

When vlc is playing or pause, Pd is blocked. So I must kill the process to stop it. It happens only with vlc as far as I know because it works with SMplayer (Mplayer) and Hydrogen Drum machine playing.
I tested with higher latency like 100ms and 200ms but it doesn't work ever with vlc.
