Running
for i in `seq 1 10`; do xterm -e ssh -Xf `hostname` xclock & done
seems to add
/usr/lib/WindowMaker/WindowMaker warning: internal X error: RenderBadPicture (invalid Picture parameter)
Request code: 154
Request minor code: 7
Resource ID: 0x4006b1

to ~/.xsession-errors. Under fvwm95 nothing gets added to that file
but i still only see about 1-4 xclocks.

As strace was out of guestion I tried
for i in `seq 1 10`; do ssh -vvvXf `hostname` xclock 2> ssh.$i.errors & done
Full output is at http://iki.fi/lindi/ssh.6.errors but I'll quote the
lines that mention xauth plus some context:
