=>Not sure.  My previous attempt at ktracing the X server resulted in an
=>almost-empty trace:
=>
=>  583      1 ktrace   EMUL  "netbsd"
=>  583      1 ktrace   RET   ktrace 0
=>  583      1 ktrace   CALL
=>execve(0x7f7ffffffc7a,0x7f7fffffda48,0x7f7fffffda58)
=>  583      1 ktrace   NAMI  "/usr/X11R7/bin/X"
=>  583      1 ktrace   NAMI  "/usr/libexec/ld.elf_so"

   The X server runs setuid root, so you lose permissions to trace
it as soon as it is executed. Try su-ing to root, then run the
ktrace.
