Re: [gpsd-dev] Major progress!

[Hal Murray]

So far it looks OK on Linux.

I'm having troubles on NetBSD and FreeBSD.

FreeBSD gets typical lost sentence problems.  So I changed WRITE_PAD from 
0.001 to 0.01
Then it hung on the second or 3rd test.  It seems easy to reproduce.

top says:
  PID USERNAME  THR PRI NICE   SIZE    RES STATE   C   TIME   WCPU COMMAND
 9021 murray      1 103    0 16116K  8216K CPU1    0   4:48 100.00% python

This morning, NetBSD also hung.  I haven't seen that this evening.

--------

The latest SHM cleanup doesn't seem to work on *BSD.  I get things like this:

(from my extra tests)

I don't know if that is a bug in their SHM implementation or we don't 
understand the rules.
