NSLog should be thread-safe.
The code you provide is incomplete and certainly won't even compile, so we
can't really tell what your problem might be.
Please write a complete testcase demonstrating what your problem is...
You can get the latest gnustep-make from svn trunk and try 'gnustep-tests
--help' to get started ...
There are example tests in $GNUSTEP_MAKEFILES/TestFramework
