92b46d9814 SystemMonitor: Show information about purgeable memory
This patch exposes some fields about purgeable memory regions.
We now also show total purgeable volatile and non-volatile memory in
the big process table.

e09a02ad3f SystemMonitor: Show thread name instead of process name
Add the thread name to CThreadStatistics and display it in the
system monitor's process model instead of the process name.

5a45376180 Kernel+SystemMonitor: Log amounts of I/O per thread
This patch adds these I/O counters to each thread:

- (Inode) file read bytes
- (Inode) file write bytes
- Unix socket read bytes
- Unix socket write bytes
- IPv4 socket read bytes
- IPv4 socket write bytes

These are then exposed in /proc/all and seen in SystemMonitor.

5b8cf2ee23 Kernel: Make syscall counters and page fault counters per-thread
Now that we show individual threads in SystemMonitor and "top",
it's also very nice to have individual counters for the threads. :^)

712ae73581 Kernel: Expose per-thread information in /proc/all
Previously it was not possible to see what each thread in a process was
up to, or how much CPU it was consuming. This patch fixes that.

SystemMonitor and "top" now show threads instead of just processes.
"ps" is gonna need some more fixing, but it at least builds for now.

Fixes #66.

9da121f837 SystemMonitor: Make all tabs except the process table lazily loaded
We now use GLazyWidget for all the secondary tabs, which makes the
program start up way faster than before.

There's a noticeable delay when you click on the "PCI Devices" tab
for the first time, but that's definitely better than always eating
that delay before seeing a window at all. :^)

35138437ef Kernel+SystemMonitor: Add fault counters
This patch adds three separate per-process fault counters:

- Inode faults

    An inode fault happens when we've memory-mapped a file from disk
    and we end up having to load 1 page (4KB) of the file into memory.

- Zero faults

    Memory returned by mmap() is lazily zeroed out. Every time we have
    to zero out 1 page, we count a zero fault.

- CoW faults

    VM objects can be shared by multiple mappings that make their own
    unique copy iff they want to modify it. The typical reason here is
    memory shared between a parent and child process.

cbdda91065 ProcessManager: Rename it to SystemMonitor
This is a more appropriate name now that it does a lot
more than just manage processes ^)

Renamed from Applications/ProcessManager/ProcessModel.cpp (Browse further)
