commit 9ea3ef26551a754df502e03002a73052f3c2fbc6
Author: Ludovic Courtès <address@hidden>
Date:   Thu Mar 6 21:41:51 2014 +0100

    utils: 'fcntl-flock' passes an errno when throwing an exception.
    
    * guix/utils.scm (%libc-errno-pointer, errno): New procedures.
      (fcntl-flock): Use it as the exception's argument.

commit f326fef8a89d02b481d7e900ef791d0108381f3f
Author: Ludovic Courtès <address@hidden>
Date:   Thu Mar 6 21:38:45 2014 +0100

    offload: Serialize file transfers to build machines.
    
    * guix/scripts/offload.scm (machine-lock-file, lock-machine,
      unlock-machine): New procedures.
      (with-machine-lock): New macro.
      (process-request): Wrap 'send-files' and 'retrieve-files' calls in
      'with-machine-lock'.

commit 827d556311b79d44fd67b4bd24cf17e5f781d502
Author: Ludovic Courtès <address@hidden>
Date:   Thu Mar 6 18:38:19 2014 +0100

    tests: Rewrite 'fcntl-lock' test.
    
    * tests/utils.scm (temp-file): New variable.
      ("fcntl-flock"): Rewrite to actually test whether the child process
      waits for the lock to be released.  The previous test was wrong
      because (1) it expected F_SETLK semantics, not F_SETLKW, and (2) it
      got EBADF because of a mismatch between the open mode and the lock
      style.

commit 56c72822a81cdf5ff4022d64a26887df427d62dd
Author: Ludovic Courtès <address@hidden>
Date:   Wed Mar 5 23:25:37 2014 +0100

    download: Perform derivations locally.
    
    * guix/download.scm (url-fetch): Pass #:local-build? #t to
      'build-expression->derivation'.
    * guix/git-download.scm (git-fetch): Likewise.
