Not entirely - the problem being that pstree always uses Cygwin PIDs which  
are not necessarily the same as WINPIDs - it would be quite useful if  
pstree had an option to display Windows PIDs.

(In fact, I had to rewrite the PIDs in my pstree output of the git-svn  
report on this list some hours earlier to the winpids to match the  
sysinternals handle output...)
