Couldn't the rotation process use file space from a different disk
partition to accomplish its work?

Would this work:
- attach to live process with a debugger
- figure out which file descriptor corresponded to the log file
- poke a program into memory at some innocuous location
- the program would copy the log file to another file (on another disk
partition)
- then the original log file could be truncated
