First a note: due to the more mature option parser I am using now instead of
GNU getopt_long, you may now use -vv instead of -v -v
If you believe it hangs whithout consuming CPU time, it cannot really be a
problem in mkisofs.
Possible debug methods:
- Run "pstack <pid>" to see a stack trace of the program
- Run "gcore <pid>" followed by "adb <path_to_mkisofs> <core.pid>"
followed by $c to see a strack trace.
