Hang in usr1_handler (ptrace issue?)

[Mike Hearn]

Hi,

Lately I've been seeing hangs of this form:

Backtrace:
=>1 0x4df8e7a2 (0x659ffb54)
  2 0x5246f507 NTDLL_wait_for_multiple_objects+0x387(count=0x0, handles=0x0, flags=0x8, timeout=0x659ffd10) [/source/wine/dlls/ntdll/sync.c:683] in ntdll (0x659ffcf8)

in other words, whilst waiting on some server object it was suspended. I
am running the FC3 kernel "2.6.9-1.681_FC3". Is this what the
previously discussed ptrace change would look like? If so I may need to
ask Red Hat to do an errata or something. I saw that in 2.6.10-rc3
another ptrace change went in, so it may be that it's now fixed.
