Hi all
Somebody from the Linux camp was pointing me to this (mis)feature
of getpass(3):
/*
* note - blocking signals isn't necessarily the
* right thing, but we leave it for now.
*/
omask = sigblock(sigmask(SIGINT)|sigmask(SIGTSTP));
While i think that blocking SIGTSTP might not be the worst idea at
all, blocking SIGINT contradicts the principle of least surprise, in
that you can't interrupt a program that's requesting a password until
you finally entered a newline.
Unless somebody objects, i'm going to remove SIGINT from the above
line.

Never trust an operating system you don't have sources for. ;-)
