yes, although it defeats rhe purpose of using an event library when you
then stop the whole program for a connect - if you know you have nothing
else to do while you connect, this is fine though.

if you want to do sth. else, do a nonblocking connect (and use a normal
libev timer and a write watcher to detect when the connect has finished).

No, you are save as long as you handle SIGALRM (remember that sigalrm
terminates your program). libev does not use sigalrm at the moment and
there are no plans for it to ever use it, at least not by default.
