I believe it does mean that data is lost.  I did the following 
simple test:
#>ssh localhost
[ Login ]
%> sleep 10; echo hi &
%> exit

I did this on
(1) OpenBSD 2.9 with OpenSSH_2.9 and tcsh-6.10.00 (from ports)
(2) Linux 2.4.6 with OpenSSH_2.9.9p2 and tcsh-6.10-5 (RH 7.1)

On the OpenBSD box (1) the exit was immediate.  "hi" WAS NOT printed.
On the Linux box (2) the exit hung, after the delay "hi" WAS printed
  then the exit finished.
