Re: [Dovecot] test program #2: mmaping

Attached another test program. I don't expect it to print any errors with any OS, but I'd like to confirm it for non-Linux SMP kernels.

(Except for OpenBSD, it doesn't work correctly in it anyway because it doesn't support mixing write()s and mmap())

6.2-RELEASE FreeBSD 2 x Intel(R) Xeon(R) CPU 5130 @ 2.00GHz (2000.08-MHz 686-class CPU)
