Actually, this is how setglobalstr() and getglobalstr() internally work,
with a hidden buffer, in which the variable name (alias the key value)
is the first word on each line (alias reacord), so that part would be
pointless to program ourselves.
To answer part of the original question: because getglobalstr() and
setglobalstr() work with a hidden file, the number of session global
variables you can add is only limited by internal memory and TSE's
disc swap space.

Yes, here you can beat getglobalstr().
Setglobalsstr() adds new variables (keys) to the begin of the hidden buffer,
so getglobalstr() can not do a binary search and is "slow".
