Apache 2.2.11 hangs on reload under NetBSD/i385 5.0_RC3

        Hello,

I'm trying to look into PR pkg/41181 which is about Apache 2.2.11 hanging
on reload. As this doesn't happen on my NetBSD/amd64 5.0_RC3 system
I've asked the submitter to send me a "ktrace" output which he was kind
of to provide. The only suspicious part I could find in it in this:

  1585      1 httpd    semop(0x230001, 0xbb9ce7a8, 0x1) Err#4 EINTR
  1585      1 httpd    SIGTERM caught handler=0x812d3be mask=0x0 code=0x0
  1585      1 httpd    close(0x10)                 = 0
  7526      1 httpd    kevent(0x10, 0, 0, 0xbb12e1f0, 0x3, 0) Err#4 EINTR
  7526      1 httpd    SIGTERM caught handler=0x812d3be mask=0x0 code=0x0
  7526      1 httpd    close(0x10)                 = 0
  1585      1 httpd    munmap(0xbabc0000, 0x1bf000) = 0
  1331      1 httpd    semop(0x230001, 0xbb9ce7a8, 0x1) Err#4 EINTR
  1331      1 httpd    SIGTERM caught handler=0x812d3be mask=0x0 code=0x0

The SIGTERM is sent because "httpd" was hung after the reload and
was restarted. Why would semop(2) block like that?

        Kind regards
