Thanks. In some cases it is clearly interaction with other processes, and killing them solves the problem. For example using ange-ftp, I got lock-ups half of the time, but killing the ftp process get me out of them.

But sometimes I got lock-ups with no apparent interaction with other processes. Then again, I don't know enough about all the Emacs internals to know when it is waiting on a separate process and when it is, say, processing an Lisp infinite loop (which I suppose gives the same behavior).
