Consider waiting a small extra delay for each syscall on commands with multiple syscalls

Hijacking system calls incurs a small (<0.1s) overhead. If a command triggers a series of several system calls, it's likely to take longer than the default vroom delay and need an explicit extra delay like `(0.5s)`.

Vroom should take into account when it knows it's expecting several system calls and account for a little extra delay per system call.
