[GE users] SGE 6.0u4 on lx24-x86 - lots of sge_qmaster entries in proc table

    [ The following text is in the "iso-8859-1" character set. ]
    [ Your display is set for the "ISO-8859-10" character set.  ]
    [ Some special characters may be displayed incorrectly. ]

May be AS 2.1 is old enough that it only has "LinuxThreads".

Since qmaster is threaded, LinuxThreads will show the threads as processes.
Newer kernels with NPTL have that fixed.
