'cdrecord -toc' or 'cdrecord -atip' unlocks tray?

[Mirco Lorenzoni <mrc.lrn@inwind.it>]

A mounted cd or dvd can be ejected, pressing the eject button on the cd/dvd 
unit, if one of the following commands is executed after the disc has been 
mounted:
            cdrecord dev=x,y,z -toc 
            cdrecord dev=x,y,z -atip 
            cdrecord dev=x,y,z -msinfo  (ejects and reloads the disc)
(<x,y,z> identifies the unit in which the disc is loaded).
Is this a specific problem of my system and/or configuration, or is a common 
problem? 

I use Linux, kernel version 2.4.31 compiled for i686/athlon, glibc 2.3.5.

P.S.
I can reproduce this behaviour with both cdrecord 2.01 and 
Cdrecord-ProDVD-Clone 2.01.01a01.
