Issues for 20070130-1143:

olbd/xrootd communication problem (Pavel)
xrdcp becomes slow if a server has been restarted while transferring data. FIXED (WK)
Usage of -f/-F flags for xrdcp
xrdcp prints lots of header info if server was restarted (WK)
new xrdcp doesn't work properly with old xrootd server (20050920 productions version) (WK)
option "-DIReadAheadSize 0" is required, but still extra bytes are written to the local file
Multistream xrdcp crashes xrootd server (FIXED 20070226-0829) (WK)
Needed to turn of async io (xrootd.async off) for Solaris (tested with Solaris 9). Otherwise got data corruption while reading files.
Proxy not stable. Needs more testing.
Questions:
Using prepare with stage option stages a file to disk. Running a stat before the prepare the file doesn't get staged in. Seen with old xrootd version used by GLAST. Needs to be confirmed with new version.
No forward of mkdir command? (WK)

my $exist = XrdClientAdmin::XrdExistDirs($newDir);
- Returns and uninitialized value if the directoy doesn't exist.
- Error message: Xrd: SendGenCommand: Server declared: Unable to locate /test/testCA; No such file or directory(error code: 3011)
  In this case it isn't really an error as the purpose of the command is to check for a dir.
bool return values: 1 for True but empty string for False.
XrdExistFiles, XrdExistDirs: If a file or directory is not found the function exit and return no value. They should return a string, with a 1 for file/dir exists or 0 if not.
