Actually I'm pretty sure Wireshark *does* perform two passes when a display filter is applied from the command line.  
It performs the first-pass on reading the file during which it applies a read-filter if supplied as well as a 
display-filter if supplied, and it does a second display-filter and dissection pass during loading of the GUI's 
packet-store (which was filled by whatever passed the first pass).
