time of logon does not seem to be dependend on the time of the error in 
our case. neither the time of starting the first cygwin shell if rdesktop 
is used. it definately isnt the first cygwin process that errors out. 
sometimes we get the error just a few minutes after logon, sometimes a few 
hours. as i already mentioned, i have the impression that it seems to 
occur more often/earlier as more users are compiling at the same time.
our nightly build, for example, broke at library ~100 out of ~300

logging in users through ssh and rdesktop are only member of "users" and 
"remote desktop users". after installing sshd with ssh-host-config the 
sshd user had the SeCreateGlobalPrivilege flag. using ssh, the cygwin and 
the windows whoami binary correctly report the username, not sshd. we had 
the CreateFileMapping problem with the default rights windows came with, 
so we added the group users to this privilege using gpedit.msc (which btw 
is not listed by 'editrights -l -u username'). these settings are still 
active.

hope this helps,
andre
