recent changes to the alert Panel made it work reliably on Linux when called
form outside the main thread.
I discovered that it isn't so reliable on netBSD! The same test application
applies: FTP from GAP in its current CVS version. Trigger an alert pane by
for example trying to upload a file in a place where you don't have
on Mac you reliably get an Alert Panel. On Linux/GNUstep you get a warning
but it works. It is indended.
On NetBSD sometimes it works,. sometimes not: nothing pops up  and I don't
get the NSLOg warning either! I keep just hitting the upload button to
triggger the event.. very strange.

In the same way when I download/upload a file the working task does some
updates (writes a string and moves theprogress bar). On linux this currently
works fine. on NetBSD it may crash:

/home/multix/gnustep-rep/gap/user-apps/FTP/FTP.app/FTP: Uncaught exception
NSInvalidArgumentException, reason: Tried to add nil to array
