[rrd-users] RRDp.pm error weirdness

while recently trying to debug a problem i was having using RRDp i
wanted to have a script act based on the error message received.  when
my script just hung i decided to take a step back and do something
simple like the following and that also hung:

RRDp::start "/usr/bin/rrdtool";
$cmd = "create buh.rrd --step 60 DS:in:DERIVE:0:10000
$RRDp::error_mode = 'catch';
RRDp::cmd $cmd;
my $answer = RRDp::read;
print $RRDp::error . "\n" if $RRDp::error;

so i decided to look at RRDp.pm and i noticed that the error handling
section sees the error and sets $ERR = 1 but doesn't return so it gets
stuck in the while(1) waiting for something to tell it to return.

am i missing something?
