/* Note: GT.M code *MUST*NOT* make use of the sleep() function because use of the sleep() function
|
||
|
|
causes problems with GT.M's timers on some platforms. Specifically, the sleep() function
|
||
|
|
causes the SIGARLM handler to be silently deleted on Solaris systems (through Solaris 9 at least).
|
||
|
|
This leads to lost timer pops and has the potential for system hangs. The proper long sleep mechanism
|
||
|
|
is hiber_start which can be accessed through the LONG_SLEEP macro defined in mdef.h.
