Hi Monks
For some time when i turn blocking off for a file handle that points to *STDERR,
it also turns blocking off for *STDIN. I am using perl 5.8.1 . Here is the code:

my $fhandle = IO::Handle->new();
if (!$fhandle->fdopen(*STDERR, "a"))
{
die("Error: Unable to open \"err\" file handle: $!\n");
}
$fhandle->autoflush(1);
$fhandle->blocking(0); 

In a:
while ( <STDIN> )
{
doIt($_);
}

As soon as we turn blocking off for STDERR, STDIN no longer blocks.
I tried to turn blocking on for STDIN with STDIN->blocking(1),
but then STDERR now has blocking turned on.

Expecting your help
