#850: jemalloc fails to init on Ubuntu 8.04

Comment(by miohtama):

 I did a clean reimaging of the server and I cannot repeat it on a new

 But this is what I believe happens:

 * The server has some faulty .so file

 * Normally this doesn't cause anything bad, as the file is not loaded and
 the error message is silently DLL loader. Because we are using system
 malloc which is safe, the error message is correctly allocated.

 * But when jemalloc is in place, the DLL loader, when loading some
 libraries, tries to allocate the memory for the error message and thus
 trying to call jemalloc which is not yet initalized

 I think the correct approach would be somehow have a special allocator in
 jemalloc before it is properly initialized.
