1 Even though SVR4 has truss, you may prefer using strace for a number
2 of reasons. Not the least of which are portability and source code.
4 The main event loop is awkward on systems for which procfs isn't
5 pollable. I think a pollable procfs is a Solaris invention so most SVR4
6 systems have this weakness. On Solaris, strace runs as a single
7 controlling process. This is a big improvement if you are debugging a
8 lot of processes at once.
10 There is no thread support but it wouldn't be very difficult to add it.
