in thread use lib './' security safe?

unshift would be bad. That puts "./" at the start of the search list, which means standard module names could be overridden by placing bogus ones in the CWD.
push @INC,"./";
Better, but it isn't going to affect use statements, since those are evaluated at compile time. So,
use lib "./";
is even better.
But best is:
use lib /some/absolute/path/that/you/control;
Update: use lib "./" is worse than unshift @INC,"./" because it also prepends "./" to the search path, but does so at compile time, where it can affect other use statements.
