It's not that `read ()' blocks but rather that `strace' fails to read
the memory region pointed to by the second argument to `read ()' (e.g.,
its `ptrace ()' call never returned).

No, ext3.

Actually, it _looks_ corrupt after X crashed.  But upon reboot + fsck (+
additional reboot if `fsck' feels like it), the file is correct.

Unfortunately I can't because (i) at that point the screen is off ;-)
and (ii) I don't have any null-modem cable to get the console output
via the serial line.

Thanks,
