No, same effect as with Ctrl-Z - short flickering of the terminal
window, but no process suspension.
While staring at the flickering, it seems to me that the content of the
window before starting vim appears for a fraction of a second, as if vim
is suspended, but then restarted immediately.
FYI, the text browser links crashes also on the first suspension (like
mutt).

ncftp can be suspended 2 times - but the third time, it starts to use up
all CPU time of the machine (starting the task manager for killing the
runaway ncftp process took several minutes) and issues error messages:
