120gcc: 1803 syscalls, 1095 con error (61%) — 919 de 923 readlink FALLAN.
121 Al piso medido de 78,7 ns por syscall, 1803 cruces = 0,14 ms sobre 30,5 ms de compilado
122 => el cruce al kernel es el 0,5% del compilado. La tormenta de rutas de T8 vale
123 MILISEGUNDOS por invocación, no minutos.
124zig cc: 3608 syscalls, sólo 214 con error, pero 1104 futex (70% del tiempo EN syscall) y 5 wait4.
125 Su perfil no es de búsqueda de rutas sino de coordinación entre hilos; el tiempo de
126 syscall que reporta strace -c es espera BLOQUEADA, no CPU.
