We are seeing this constantly on our build slaves during gcc and ARM compilation:

I've completely turned off the Response Time check, bumped the heap size to 512MB (monitoring indicates that this is ample), ensured that the slave is using Oracle JRE (1.6.0_45-b06).
Slave is Ubuntu 10.04 (fully updated) 4 core, 1GB RAM living on Suse KVM host. Monitoring indicates that CPU consumption and load average are definitely high (compilation, etc).
This is a really ugly issue. What is the status of development?
