What exactly does the -W flag do?

Hi,

What exactly is involved when the user specifies the -W flag?  For me,
after doing so and invoking SOOT on some simple code, the amount of memory
it consumes sky rockets to the point where the JVM returns
java.lang.OutOfMemoryError (top reports that it consumes more than about
80 Mb and then dies).

Thinking that this could be a problem with a transforms/optimizations done
in the whole program phase, I turned them all off with the following flags
to SOOT:

-p wjop.smb disabled -p wjop.si disabled -p wjtp2.ra disabled

Still, the amount of memory SOOT consumes sky rockets.  What further
analysis is done when the -W flag is set?

Keep in mind that this does not happen for all programs.  Code which does
not import any packages run through SOOT with -W perfectly, while those
that do import packages blow up in terms of memory usage.  Could this mean
that a call graph is being generated for the whole application and all
packages...causing the memory explosion?  Something else?

Thanks in advance!
