func LiveProcs(prefix string) (map[int][]string, error)

LiveProcs is similar to `man 1 fuser`; it takes a prefix and returns a map of PIDs of any processes accessing files with the prefix. A process is considered to be accessing a file if it has an open file descriptor directly referencing the file, has an open Unix socket referencing a file, or has a file mapped into memory. This operation is inherently racy (both false positives and false negatives are possible) and hence this should be considered an approximation only.
