You can have multiple fd's open at the same time, which is a lot more 
convenient. 

I will _not_ add a fcntl-like or ioctl interface to this. They are ugly 
_and_ there are security issues (ie if you pass on the fd to somebody 
else, they must not be able to change the signal mask _you_ specified).

One of the reasons for the "flags" field (which is not unused) was because 
I thought it might have extensions for things like alarms etc.
