Hi Jeremy,

We tried to reproduce the situation caused the first post about a memory 
leak. My  colleague told me, that it is necessary to have a printer 
window open displaying several print jobs.

I've attached the gzipped 26k file. If it doesn't make it to the list, I 
could resend it to you personally.

Compared to the first post we had *before* Volkers patch lots of:

Printer Entry [-40000784]      contains     26 bytes in   2 blocks 	 
          	.name                          contains     26 bytes in   1 
    struct samu                    contains    543 bytes in  26 blocks 
        	struct passwd                  contains     71 bytes in   6
[...]

and now we only have

Printer Entry [-40000784]      contains     26 bytes in   2 blocks 
      	.name                          contains     26 bytes
Printer Entry [-40000784]      contains     26 bytes in   2 blocks
         .name                          contains     26 bytes in   1
Printer Entry [-40000784]      contains     26 bytes in   2 blocks
         .name                          contains     26 bytes in   1
[...]

If these entries are a leak I can't say - but you will know.

Thanks,

Martin
