#8601: Running alert with execl from app launched by tracker results in infinite
loop

Use this very simple application :
{{{
int main(void)
{
execl("/bin/alert", "alert", "alert", "alert", NULL);
}
}}}
When run from terminal, everying works as expected.
When run from Tracker, alert gets launched, but apparently gets an invalid
port.
Notes from IRC chat about it :
<AnEvilYak> alert's BApplication looper seems to have an invalid port
<AnEvilYak> BLooper::ReadRawFromPort() calls port_buffer_size_etc() which
returns a negative value
<AnEvilYak> because of the way things are returned up the chain, this
leads BLooper to think it has a message even though it doesn't
Since alert is then sucking 100% CPU, this is quite annoying to debug on
my single-core machine.
