fcntl() are coalesced. One system does not coalesce locks.
According to PASC Interpretation reference 1003.1-90 #50, either
behavior conforms to POSIX.1. XPG4 adds no extended specifications
on this point.
This problem is reported in the VSX Release notes and only affects a
single system. This problem would require considerable changes in the
user test set-up in order for a correction to be effective.Test Output ************************************************************************
