I didn't keep the generator strace file for this failure, sorry, but I
have been able to generate a new set of straces for the same problem:
when rsyncing two directories which contain one big ,v file, rsync is
stuck after having transfered the big file correctly.

The command line is something like :
mordred$ rsync -e cvslrsh -dgopv --del path/ hirondelle:path
and the cvslrsh script is calling rsh to connect to hirondelle, then
cvslock to lock the destination path before calling rsync with the given

On mordred (the initiator and sender side), there is one rsync process
which pid is 17155.
On hirondelle (the client and receiving side), there are two rsync
process, the first has pid 14745, the second has pid 14746.

Please, find the three strace files here 
(there are too big to be sent by email), the pid is in the filename. 
Note that the two computers have 9 hour difference in the time because 
they are not in the same time slice but the synchronization is quite good.

Thank you to take a look at this, I hope my report is correct now and
that you will be able to do something with it.

Best regards.

P.S.: sorry for the delay in the answer, I first tried to sent the 
strace files attached but it seems that it doesn't work.
