It can also sometimes be useful to run your program using strace.
The sequence of syscalls can be excellent clues about the progress
(or lack thereof) your program is making.  Many times I've solved
mysterious problems after seeing failed attempts to open config
files, pipes, sockets, etc that the program itself never mentioned.
