I just had to post how much I love valgrind.
I have a long live C program that once ran for 400 days straight serving out requests for my website. It ran for so long that “ps’ just showed the year that it was started 
Anyway enhancements over the years have introduced some memory leaks, and within a number of hours, I had fixed all the leaks. Some of the changes were in code I hadn’t touched for years. It just makes things so easy. So .. thanks Julian!
