• max. memory used (rss, locked, virtual memory, data, stack)
• max. file size (& core size)
• max. user processes
• max. CPU time
• rlimit - like ulimits for the entire vserver
• Total RSS, VM, Locked memory
• number of processes
• number of open file descriptors, sockets
• Shared memory, SHMs
• CPU limits - O(1) Token Bucket Scheduler in "Hard" mode
• Disk Limits
• Per-Context Quotas - experimental (suffers from a poor API)
