Can this be explained?  Something seems very wrong with what this program is
dong. The log produced by tracing a hello world program is 1,205,390. 
That's a US million!

Wed Dec 15 05:25:52:> cat hello.m
<< GUIKit`

TracePrint[GUIRunModal[Widget["Label", {"text" -> "Hello World!"}]]]
    
Exit[]

Wed Dec 15 05:25:53:> math < hello.m > hello.log

The code without the trace produces this:
