Hi Mark,
I forgot the demo:
# cd tests;make deleted deleted-lib.so;./deleted&p=$!;sleep 0.1;rm deleted
deleted-lib.so;../src/stack -m -p $p
[...]

Also not completely sure if ' (deleted)' should be left there but I think it
is right as long as Linux kernel finds it right there. I had there first:
size_t last_file_len = strlen (last_file);
const char deleted[] = " (deleted)";
const size_t deleted_len = strlen (deleted);
if (last_file_len > deleted_len
&& strcmp (&last_file[last_file_len - deleted_len], deleted) == 0)
last_file[last_file_len - deleted_len] = 0;
Thanks,
Jan
