Note that, by convention, the second argument should normally also be the
filename (the second argument will be available to the program as
argv[0]), e.g.:
os.execl('filename.exe','filename.exe')
If successful, the exec* functions don't return. On Unix, the new program
replaces the existing program in the current process. IIRC, the Windows
version executes the program in a child process then exit()s upon
completion.
The exec* functions probably shouldn't be used within a program which uses
any of the more complex OS features (e.g. GUI), as they will block event
processing, background threads, etc.
