FYI,

I've been testing new features I've added to the Python
implementation of strace, and I'm pretty happy with them:

 1) I've added code to keep track of the paths associated with file
    descriptors by watching for open/close/dup/dup2/clone calls.

 2) I've added a command-line option to display the associated path[s]
    for all syscalls that have file descriptors as parameters.

 3) I've added a command-line option to filter the display of syscalls
    based on a list of paths.  It will output only syscalls who's
    parameters include either a one of the specified paths or a file
    descriptor associated with one of the specified paths.

That required a total of 90 lines of code.

I'm going to start working on re-implementing the above in C...
