Do you mean that something like this happens :

Say you have 3 systems: A, B, and C
Run update-grub on A and it finds A, B, and C - so 3 entries
Run it then on B and it find the 3 entries in A's grub.cfg and builds it's own 
containing B, A, C (found directly) plus A, B, C copied from A's grub.cfg.
Run it on C and you get C, A, B (found directly) plus A, B, C copied from A's 
grub.cfg plus B, A, C, A, B, C copied from B's grub.cfg.

Thus you quickly end up with C, A, B, A, B, C, B, A, C, A, B, C - that's 12 
entries after just once round the OSs. This will quickly run out of control, 
growing at an ever faster rate.

If that's what is happening, then that suggests a lack of (effective) duplicate 
detection in update-grub - or perhaps there's none at all on the basis that you 
should not be having multiple installs like that ?
