A one-liner: Why doesn't alarm interrupt <> ?

[David Morel]

Hi all,

Why doesn't the following program terminate?

alarm 1;
<STDIN>;

It seems that alarm does not interrupt the <> operator. Why not? And
more importantly, is there any way to interrupt the general <handle>?
Surely there must be a way... thanks in advance,

It works fine for me... Under linux and Solaris.

alarm 1;
<STDIN>;

perldoc perlport says:

alarm SECONDS
alarm Not implemented. (Win32)

In my docs. Which would probably cause it not to work.
