Yes, there is of course a race between soffice starting to listen on the 
socket you passed it with the -accept argument and your code calling 
connect.  See, for example, the for -- try -- catch NoConnectException 
loop in unotest/source/cpp/officeconnection.cxx for how to live with 
that race.

That note is misleading.  The simplified bootstrap mechanism internally 
still uses a socket connection.  See
