Error spew when cancelling uninstallation that is blocked by another task

[ryandesign (Ryan Carsten Schmidt)]

I told MacPorts to uninstall inactive ports. This caused a "Waiting for lock" message, because I was also installing ports in another terminal window. So I cancelled the uninstall operation by pressing Control-C. The only output I expected to receive was the two characters "^C" but I got many lines of output in addition:

$ sudo port uninstall inactive
Waiting for lock on /opt/local/var/macports/registry/.registry.lock
^CSIGINT signal received
    while executing
"adv-flock $lockfd -exclusive"
    (procedure "registry::exclusive_lock" line 20)
    invoked from within
"registry::exclusive_lock"
    (procedure "lock_reg_if_needed" line 11)
    invoked from within
"lock_reg_if_needed $action"
    (procedure "process_cmd" line 25)
    invoked from within
"process_cmd $remaining_args"
    invoked from within
"if { [llength $remaining_args] > 0 } {

    # If there are remaining arguments, process those as a command
    set exit_status [process_cmd $remaining..."
    (file "/opt/local/bin/port" line 5576)
$
