#1 Disk I/O analysis

[tromer]

One potential application for SysCallTrack is analysing
disk I/O ("why is my server using the disk so much?").
It could then replace the broken and closed-source
FileMon for Linux.

Required extensions:
1. Support for file-related syscalls, in particular
read() and write().
2. Translation of local pathnames into absolute pathnames
3. Translation of file descriptors into pathnames
(e.g., using the /proc/$pid/fd/$fd symlinks).
4. Wildcard or regexp filters, applicable to the result
of the above translations.
