`.    (a period)'
          . FILENAME [ARGUMENTS]
     Read and execute commands from the FILENAME argument in the
     current shell context.  If FILENAME does not contain a slash, the
     `PATH' variable is used to find FILENAME.  When Bash is not in
     POSIX mode, the current directory is searched if FILENAME is not
     found in `$PATH'.  If any ARGUMENTS are supplied, they become the
     positional parameters when FILENAME is executed.  Otherwise the
     positional parameters are unchanged.  The return status is the
     exit status of the last command executed, or zero if no commands
     are executed.  If FILENAME is not found, or cannot be read, the
     return status is non-zero.  This builtin is equivalent to `source'.

Why don't you try it, and let us know?
`ulimit -a' reports all current limits.
