I'm planning on taking the data that femon puts out, and pulling it
into a graph or database. In order to do that, I needed a date/time
stamp. Here's my patch to femon.c to make this happen:

printf("FE_HAS_LOCK");
Right now I have this running in the background, dumping to a log
file. Then I can go back and look in the log file when I have a
problem.
As always, works for me....
