Description:
for large systems malloc() system call can take a long time, this will cause ndbd to go down on watchdog timeout.  Setting watch dog timeout higher to avaod this makes the timeout to large to make any use when system is up and running

this is especially true when using lock pages in main memory

How to repeat:
.

Suggested fix:
have separate watchdog timeout for memory allocation start phase
