This happens if mod_perl is compiled as a DSO, this will not happen if
mod_perl is compiled statically into the httpd core. I believe that this
has something to do with the way perl allocates variable and stashes
them away in static or global variables. If mod_perl is compiled as a
DSO, httpd will completely unload and reload all DSO's on a restart and
cause all global/static variables to be reset to NULL, forgetting all
traces about previously allocated memory. If mod_perl is built
statically, it will not be reloaded and thus all global/static variables
persist and perl will re-use the memory allocated.
