But the network package doesn't try to let you work with raw file descriptors elsewhere (e.g. send and recv.) I'm not saying that functions on Fds aren't useful, they are, just that the network package is the wrong place for them. I'd put them in the unix package.
Putting them in the unix package means they won't be available for Windows (where I needed them the most).
I use Int64 for Microseconds, to avoid truncation when Int is 32 bits. 2^31-1 microseconds is only 35 minutes and 47.483647 seconds. Perhaps I should just use Int and Int64, and be sure to document what units are used.
We should use whatever the underlying OS uses. If that's a 32-bit int, using a 64-bit int on the Haskell side doesn't help us. The goal here is to faithfully match the underlying APIs.
For SO_RCVTIMEO and SO_SNDTIMEO, Windows and Unix use different representations. Windows uses DWORD (unsigned 32-bit) milliseconds, while Unix uses struct timeval, which has microsecond precision. -Joey
