smp and ptrace()

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Are there ant know issues/workarounds for ptrace() with MP kernels?

I'm asking because, while working on a gdb 6.1 package, I've been running the
gdb testsuite. I noticed that the test results vary each time I run the
testsuite unless I execute the testsuite while running a single-processor
kernel. A very noticeable variation occurs in the tests of signal handling.

If there is a more appropriate list for this enquiry, please let me know.

Thank You.
