Copying a large file drops to KDL

[diver]

While trying to copt video file (350Mb) from R5 partition to haiku it brings me to kdl. After reboot i retry to do the same with the same result. Tested on real hardware with rev17159.

Drops to KDL with: PANIC: vm_allocate_page: out of memory! page state = 4

Its happening in rev 20288 too.

With hrev22317 I no longer get KDL but tracker freezes in the middle of the copy. I made 8 copies of the haiku.image file which is 100meg, and then tried to copy all 8 to a new folder on the same partition. It copies the first 5 files ok and then gets to 61 meg on the 6th file before freezing up. Pressing F12 will let me get to KDL. If I only copy 5 files and then try copying 2 or 3 more I also get this freeze. I see that there's been more work on the vm since hrev22317 so I'm assuming this is activly being worked on. I'll check it again in a few more days. Seems like progress is being made, but as of hrev22317 not working correctly yet.

With hrev22813 I was able to copy a 100meg haiku image file several times, creating 20 copies of it. The when trying to copy those 20 copies to a new folder it got about half-way (around 1Gb) before droping into kdl with a "page requested but there is none" error. After creating the 10th copy I started getting the missing icon bug. So the error is different than before but still not fixed.

Fixed since some time. It doesn't crash anymore, and it doesn't deadlock. There may still be other problems, but the most important things are done.
