(push_int64 fails in gethrtime()) After being killed (by poweroff, etc) Roxen reloads continuously

In Roxen 2.1.185, when the server is stopped by power failure, Roxen
sometimes (not always) repeatedly fails to start.  It will appear to start
normally, with:
: Removing old .o files (defines or pike version changed)
: Starting the Roxen WebServer.
: Using configuration from ../configurations/, storing the debug log in
../logs//debug/default.1.
: You can use the administration interface in the server to get debug info.
: Forked start script, pid 4047.

...but the Roxen processes continually restart, with this as the
"default.1" log:
12:42:15  : ----------------------------------------------------------
 0m 0.0s  : Pike v7.0 release 268, Roxen WebServer 2.1.185
          : Loading pike modules ... Roxen loader failed:
          : Wrong type of object, cannot convert to mpz.
          : Unknown program: `|(object)
          : base_server/roxenloader.pike:1473: do_main(1,0)
12:42:15  : base_server/roxenloader.pike:1206:
do_main_wrapper(1,({"/usr/local/roxen/server/base_server/roxenloader.pike"}))
 0m 0.6s  :

...and there it stops. Doing a "tail -f default.1" brings this again, but with a different time.

This may not actually be a bug, but even if it is not, it seems to me that Roxen should recover from being killed (as any other Unix program would).
