This is only true for multiple concurrent read accesses.  Multiple concurrent
read accesses are also safe for the NSS cert and key databases.  The
problem only occurs when there is a concurrent write access.  Most
NSS-based server applications open the NSS databases in read-only
mode, so they can run with multiple processes safely.  But client applications
such as Firefox and Thunderbird open the NSS databases in read-write
mode.
