+/* Why this tool is used:
+ *
+ *   In order to test webfuse as a fuse filesystem, file system operations should be made.
+ *   To check for memory leaks, valgind (memcheck) is used.
+ * 
+ *   Early tests discovered some ugly behavior of valgrind:
+ *     - valgrind intercepts syscalls like open, read and write
+ *     - valgrind does not expect that syscalls are handled within the process to be checked
+ * 
+ *   There is a more or less (un-) documented switch, which changes valgrind's bevahior, but
+ *   this caused other problems.
+ * 
+ *   The second approach used GTests's death tests. Death tests were used quite a while, 
+ *   until we discovered a configuration bug when running CTest:
+ *     - memory leaks did not lead to test error
+ *   
+ *   After fixing CTest configuration, memory leaks within the death tests were shown.
+ *   Which is correct, since death tests pematurely exits the program an therefore no
+ *   cleanup is done.
+ * 
+ *   Finally, it was decided to use good old popen together with this tool.
