Fund: TempFS: filling the temporary partition causes system freeze

For example, CrashDaemon core dumps can fill the disk, eat all memory, and freeze the system.

Eventually FinalizerTask kicks in:

Note the climbing memory usage:

Reproduce:

Run crash -d 100 times

$ cat ../Base/home/anon/crash.sh
#!/bin/sh
crash -d
crash -d
