That's not in itself an argument in support of writing threaded code
if you don't have to.

I spent much of the last year developing thread-checking tools
in the Valgrind framework (Helgrind), and testing them on serious
software.  From that I would say that practically all serious
multithreaded software is riddled with threading bugs, mostly
data races and inconsistent lock orderings (potential deadlocks).
