           Summary: RunSafely.sh doesn't run safely
           Product: Build scripts
           Version: 1.6
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Makefiles
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rspencer at reidspencer.com


RunSafely.sh attempts to use the ulimit command to limit cpu/file size/core
size, etc when test cases run. However, on almost all Unixes the ulimit command
is part of the shell and the way RunSafely.sh invokes them, it occurs in a
subshell separate from the actual command being tested. Consequently, things are
not run 'safely'. 

Using the "eval" command works on Linux but not on Darwin. Its possible that we
could arrange it to run just as:

( ulimit ... ; command )

That should work on all shells.
