DTrace was created by Sun in OpenSolaris to allow developers to write simple scripts in order to probe and instrument executing programs in a way not possible otherwise. One of the advantages of DTrace is that it allows you to turn on probing when you need it, but not incur an execution penalty with regard to performance (i.e., when probes aren't being scripted, they aren't run). This requires developers to add "probes" to their source code. For example, if you wanted to know when a particular function is entered/exited, get info about what happened, etc. you could add probes to the particular function. Writing the probes is not difficult, however there are hundreds or thousands of probes that Mozilla would like across its code base.
