Just use fork(), it's cheap on Linux, certainly cheap enough for most
uses.

One example of using it is the gnome_execute_async() function in
libgnome, you could look at that code.

Also a UNIX programming book will have examples; try Linux Application
Development, Advanced Programming in the UNIX Environment, or
Beginning Linux Programming, those three are all worth owning.
