The hang in TestShell happens at this fgets:
http://src.chromium.org/cgi-bin/gitweb.cgi?p=chromium.git;a=blob;f=webkit/tools/test_shell/test_shell_main.cc;h=37c26bcff0bc9475f051cc0025b688109ed816ca;hb=HEAD#l316

If for any reason the first char of: filenameBuffer is 0 we can hang:

 324           if (!*filenameBuffer)
 325             continue;

This started happening more with my unicode changes, because we started sending
unicode bytestreams to test_shell on some systems by mistake.  If the first
byte left in the buffer is ever 00, then it hangs forever.  That could happen
if IO got interupted due to process switching, etc.
