The comment says something about backwards compatibility, so we'll have to approach the issue with care but having 0 as the error value is flabbergasting to me.

Re: [Pharo-project] Fwd: [Pharo-users] 3600 seconds seconds = 0 ???

by Guillermo Polito

According to the pdf in here http://wiki.squeak.org/squeak/172 Duration may have ... asSeconds Answer the total number of seconds in the length of time represented by the receiver. ... days Answer the number of complete days in the receiver. hours Answer the number of complete hours in the receiver. minutes Answer the number of complete minutes in the receiver. ... seconds Answer the number of seconds in the receiver. So maybe the best thing to do is to correct the comments and extend the api. Should I open a ticket?

I thought the world was not display, not Bitmap was instanciated, etc... OK, that is a different question, sorry. Isn't it so that these Bitmap instances are just regular Smalltalk objects that live the Smalltalk heap and that by definition all live Smalltalk objects get saved into the image file ? I don't think they are different from regular arrays. Running -headless (actually -vm-display-null -vm-sound-null) just instructs the VM to connect to a dummy (null) display and sound device, so that display operations have no effect, as far as I understand.
