Perl doesn't wait when remote debugging XML-RPC

[cpjust]

Hi,
I have some perl code that calls functions on a Java server over XML-RPC. I enabled remote debugging in Eclipse and set a breakpoint in the function I'm debugging, and when I run my Perl script, Eclipse hits the breakpoint and lets me step through, but the Perl script doesn't wait until I step through the function, it immediately continues running.
I have no idea why it does this.
In the new() function of the XMLRPC API perl object there's a line that says:

$self->{timeout} = 30;

I tried adding a few 0's to the timeout, but it makes no difference.
How can I make Perl wait so I can properly debug this code?

NOTE: I'm using the Perl XML::RPC module, not the RPC::XML module.
