+There are is some memory leak in [[`exec`|hurd/translator/exec]].
+
+
+# I
+
+After twelve hours worth of `fork/exec` ([[GCC]]'s `check-c` part of the
+testsuite), we got:
+
+      PID  UID  PPID  PGrp  Sess TH  Vmem   RSS %CPU     User   System Args

+
+The *RSS* seems a tad high.  Also the system part of CPU time consumption is
+quite noticeable.  In comparison:
