Tcl Source Code

Not so fast, because seems to be not so easy to fix...

That fixes a leak only if I give this line direct in stdin inside tclsh:
% time {file exists [string trim "C:/example.txt "]} 100000

If I do the same in a file (for example "test"), and execute it via `source test`, it leaks again.
Possible another constellation regarding of objects, or refcounts (history involved) or literals, etc.

Very strange also, that the tests have different execution times (constantly  reproducible):
- with leaks (% source ...): 16.03923 microseconds per iteration
- w/o leaks (% time direct): 90.1751 microseconds per iteration

But a 1 year older branch does the same without leaks within 15ms also!
