hi

i've tried to push a bunch of patches from my local repo to a server
one, and darcs just hanged. then i tracked down that there is a
"special" patch that causes the hang

if i do a "strace -p" on the server's darcs process, then i get the
following loop:

--- SIGVTALRM (Virtual timer expired) @ 0 (0) ---
sigreturn()                             = ? (mask now [HUP INT ABRT PIPE
TERM])
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [HUP INT ABRT PIPE TERM], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [HUP INT ABRT PIPE TERM], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [HUP INT ABRT PIPE TERM], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [HUP INT ABRT PIPE TERM], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, [HUP INT ABRT PIPE TERM], [], 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
--- SIGVTALRM (Virtual timer expired) @ 0 (0) ---
sigreturn()                             = ? (mask now [])

and so on.

here is the repo (can be darcs get'ed):

here is the patch i'm trying to apply:
