Very slow detaching

[marcinslusarz]

For example "vltrace ls" take 24s to finish.

Possible solutions:

• fixing the underlying issue :)
• multi-threaded detaching
• daemon mode (one background process waiting on Unix socket and another one controlling it)

Another idea is to use per syscall tracepoints - detaching from them should be faster than from kprobes.
