Has anyone an explaination for why I get such different results from running the same piece of code as a one-liner (or in a program) and running it under the debugger? 

P:\test>perl -MTime::HiRes=gettimeofday -le"print scalar gettimeofday(
+) for 1 .. 10"

I am at a complete loss to understand why the resolution would become so "blocky" under the debugger?
