Somehow we've got into an infinite loop here...

so we're trying to execute user code with a space id of 0, and this is just
not going to work.  two questions:  1) how did this happen?  2) why isn't
the process being killed?

$ ldd `which make`
        librt.so.1 => /lib/librt.so.1 (0x4002b000)
        libc.so.6 => /lib/libc.so.6 (0x4004d000)

        /lib/ld.so.1 => /lib/ld.so.1 (0x40000000)

inside libpthread, which is slightly suspicious, I suppose.
