This is a bug report for perl from stefan@puce.campus.luth.se,
generated with the help of perlbug 1.34 running under perl v5.8.1.

<CODE>
print 'Called from '. (join ' : ', caller ). ' at line '. __LINE__." \$!: $!.\n";

my $schack = <RSnaps>;
chomp $schack;
print "In Snaps1:\$!: $!. gameStatus: $gameStatus, Schack: $schack\n";
<\CODE>

<OUTPUT>
Called from Net::Telnet : /usr/local/lib/perl5/site_perl/5.8.1/Net/Telnet.pm : 2123 at line 103 $!: Interrupted system call.
In Snaps1:$!: Bad file descriptor. gameStatus: 3, Schack: oGame over
<\OUTPUT>

The code is called from a caught $SIG{USR1} not realy from Telnet.pm but the
script is usually waiting in a Telnet::getline() when the signal arrives.

This did not happen in 5.8.0 but it does with 5.8.1.

I have _fixed_ this with:
undef $! if $! eq 'Bad file descriptor';

It dies in the Telnet module if I leave it as it is.
