[uml-user] RT Signals

[Andy K. <ise...@ai...>]

I'm setting up a RH7.2 image that is running on a 2.4.13-4um kernel.
However, mysqld seems to be taking up 100% cpu time. When straced there
seems to be a lot of rt calls - For example -

rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGINT, {0x806fb30, [], 0x4000000}, {SIG_IGN}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigaction(SIGINT, {SIG_IGN}, {0x806fb30, [], 0x4000000}, 8) = 0
rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
rt_sigprocmask(SIG_BLOCK, NULL, [], 8)  = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0

Is this because these calls are not implemented in UML yet?
